Provided are a cultivation unit and a cultivation system which enable easy cultivation of a plant in a culture medium without requiring a cultivation bed that occupies a large footprint, and enables cultivation of a plant which can be unitized. This cultivation unit 10 comprises: a cylindrical body; a liquid distribution part which is disposed lateral to or around the cylindrical body; and a culture medium housing part which is disposed lateral to or around the cylindrical body and below the liquid distribution part. The liquid distribution part is for supplying liquid to a culture medium within the culture medium housing part and is provided with a first connection part that allows liquid to be supplied to the liquid distribution part through the interior of the cylindrical body. The liquid can be discharged through the cylindrical body, by a second connection part that is for discharging liquid from the culture medium housing part into the interior of the cylindrical body.

[Problem] To provide a planar material that can easily be modified to a variety of three-dimensional shapes, a method for producing the planar material, a three-dimensional body, and a method for producing the three-dimensional body. [Solution] A planar material 100 includes a plurality of planar units 10 provided in the same plane. The shape of the planar units 10 is that of a polygon that can be tesselated, and there are one or a plurality of types of shapes of the planar units 10. The planar units 10 are positioned in a tesselated state. Vertex portions of adjacent polygonal planar units 10 are joined to each other by a joining part 12. Through-holes 14 are provided in regions equivalent to the edges of the adjacent polygonal planar units 10 other than the vertex portions.

Provided are an advertisement device and a display body having a novel design. A display body 100 comprises a light source 10, a light diffusion unit 20 through which light from the light source 10 is transmitted, a transparent body 30 which is provided over the light diffusion unit 20 and through which light that has been transmitted through the light diffusion unit 20 is transmitted, and a space unit 22 provided to at least part of a space between the light diffusion unit 20 and the transparent body 30. An upper display surface of the transparent body 30 is configured so as to comprise one or more flat surfaces and/or one or more curved surfaces. As one example, an adhesive layer is not interposed between the light diffusion unit 20 and the transparent body 30, and the light diffusion unit 20 may be constituted of an opalescent light diffusion unit.
