Abstract: In a sensor attachment structure, a lead wire connecting a sensor is pinched in a pinch portion provided at a tip side portion of an extending bar, proximate to the sensor. The pinch portion has a protrusion that protrudes from the end surface of the pinch portion toward the sensor. A contact surface of the protrusion is inclined toward the sensor from a protruding direction of the pinch portion to have an inclination angle equal to or larger than a deflection angle that is formed at the tip side of the extending bar against the extending direction of the lead wire. Accordingly, even when a tensile force F is exerted to the lead wire opposite to the sensor side, a component force of the tensile force F along the contact surface becomes zero or is directed to the base of the pinch portion.

Abstract: An acceleration sensor is disclosed which includes a capacitance-type acceleration detection element mounted on a ceramic base plate. The element comprises a movable electrode mounted between a pair of fixed electrodes. Acceleration of the sensor in a measurement direction causes the movable electrode to move relative to the fixed electrodes and the element has opposite ends in a direction perpendicular to the measurement direction.

Accordingly, the mounting surface of the acceleration sensor is parallel to the direction of acceleration to be detected. Thus the acceleration sensor can be surface-mounted on a printed board, and more be easily mounted in an automobile air bag control system or the like.
