A spin transistor 1 is a spin transistor 1 having a source S of a ferromagnetic material, a drain D of a ferromagnetic material, a semiconductor SM on which the source S and the drain D are disposed and which forms a Schottky contact with the source S, and a gate electrode GE disposed through a gate insulating layer GI on the semiconductor SM, wherein a tunnel barrier insulating layer TI constituting a tunnel barrier is interposed between the semiconductor SM and the drain D.
