Abstract
An electronic device such as a semiconductor pressure sensor is provided which has a buffer disposed within a resinous casing. Terminals extend through the casing and connect electrically with an electronic element mounted on the casing through wires. The buffer is made of a material having a coefficient of thermal expansion smaller than that of the body of the casing, thereby decreasing undesirable movement of the terminals leading to fatigue of the wires which arises from a change in temperature of the casing. This minimizes a drop in mechanical strength of the wires caused by thermal cycling to which the casing is subjected.
