Abstract
The present invention has for its object to provide a photo coupler which is operable with high sensitivity, high speed, low voltage and small current. To this end, a photo detector (13, 20, 33), which is coupled with one light emitting element (11, 21, 31) through a light transparent insulator, is formed by any one of a static induction transistor, field effect transistor and a static induction transistor.
