Abstract
A reference voltage generating circuit is constituted by resistors RE and RF each having a resistance not influenced by an application of pressure. The reference voltage generating circuit is connected between one and the other ends of a bridge circuit. A failure judgement of the bridge circuit is performed based on a comparison of a voltage difference V between two midpoints B and C of the bridge circuit and voltage differences V and V between a reference voltage level of the reference voltage generating circuit and the voltage levels of two midpoints B and C.
