Abstract: A pressure sensitive electric transducer including a solid-state device whose electric characteristics vary in response to application of an input pressing force to an operation area thereof by a rigid body pressing member in the form of a minute sphere. The pressure receiving area of the solid-state device is provided with a soft metal film and the rigid body pressing member is provided with a metal film capable of forming a eutectic alloy with the soft metal film on the surface of the solid-state device, the two metal films then being bonded together by thermo-compression bonding thereby bonding the minute sphere to the operation area of the solid-state device.
