As one of the electronic functions of organic semiconductors that have not been yet utilized, the giant Seebec effect which was discovered by our group is discussed. This is a unique phenomenon which cannot be elucidated by conventional thermoelectric theories and the Seebeck coefficent eceeds 0.1 V/K. In organic semiconductors, not only a charge but also a lattice vibration tends to be confined in a molecule. The interaction between them is considered to produce the characteristic thermoelectric effext in a specific condition.
