Provided are a water content measuring device and a cereal dryer with which it is possible for a switching operation to be performed easily even if a grain size changes as a result of a change in the type of cereal of which the water content is to be measured. Thus, according to the water content measuring device in an embodiment of the present invention, each holding opening (43a) in a plurality of grain moving plates (43) is formed with a mutually different size, corresponding to the size of the grain to be held thereby, and when a prescribed operation occurs, the holding openings (43a) pass initially over mutually different communicating holes (42a1, 42b1). In this way, when changing the size of the grains of which the contained water content is to be measured, the grains introduced into a hopper (41) can be supplied to a corresponding water content measuring unit (31) by changing only the grain moving plate (43), and therefore a reduction in the number of components can be achieved, and erroneous setting when measuring the water content of the grains can be prevented.
