Abstract: A laminated multilayer electric circuit is comprised of wafers having each internal electric circuits and laminated one after another. A signal transfer circuit used in the laminated multilayer electric circuit for transfer of signals between the wafers through an electrostatic capacitor has a receiving circuit of sufficiently high input resistance for receiving a signal from a capacitance electrode forming the electrostatic capacitor, and a circuit for clamping the level of the signal substantially within the input amplitude for the receiving circuit. The signal transfer circuit permits the signal transfer to be performed not through a flip-flop or the like and consequently at high speeds.
