Beschreibung
Zusammenfassung:	A sensor unit includes a pressure sensor 1, an acceleration sensor 2 and a signal-processing circuit 3, which are disposed on the bottom surface of a lead 4 to form a line in the longitudinal direction of the sensor unit. The pressure sensor 1 and the acceleration sensor 2 are disposed at respective symmetrical positions with respect to the center of the signal-processing circuit 3 in the longitudinal direction of the sensor unit. Each of the pressure sensor 1 and the acceleration sensor 2 has substantially the same height dimension. The sensors 1, 2, the signal-processing circuit 3 and the lead 4 are sealed with a molded body 8, in such a manner as to allow lead terminals 4a of the lead 4 to protrude outside the molded body 8. The signal-processing circuit 3 is operable, based on a signal from the acceleration sensor 2, to control the ON/OFF action of the pressure sensor 1.
