Abstract
A field-effect transistor includes a semiconductor layer (14) having a portion functioning as a channel region. The semiconductor layer (14) includes, as its constituent components, a plurality of electrically conductive microparticles (52), organic semiconductor molecules (53) bonded to the microparticles (52) so as to link the microparticles to one another (52), and cyclic molecules. Each of the organic semiconductor molecules (53) includes a π-electron conjugated chain as its main chain, and the π-electron conjugated chain is insulated by cyclic molecules.
