An element body of a coil component is composed of a magnetic powder-containing resin including magnetic powder, and an end portion of a terminal electrode extending parallel to a mounting surface protrudes from an edge on an end surface side. Therefore, the end surface of the element body is less likely to receive mechanical stress, for example, during a wet etching process or a barrel polishing process. In particular, in a region near the mounting surface where the terminal electrode protrudes, the end surface of the element body is less likely to receive stress. Thereby, the magnetic powder of the magnetic powder-containing resin is less likely to be fallen off on the end surface, a decrease in the magnetic properties of the element body is suppressed, and an improvement in coil characteristics such as an inductance value is realized in the coil component.

Therefore, all of the side surfaces of the element body are difficult to oxidize as a whole surface, deterioration of the magnetic properties of the element body due to oxidation of the magnetic powder is suppressed, and in the coil component, improvement of coil characteristics such as an inductance value is realized.
