ABSTRACT:
An acceleration sensor includes a case having a bottom part, a pair of opposed walls substantially perpendicular to the bottom part, and a pair of first projections located on the bottom part. The sensor further includes a detection section attached to the case via the pair of first projections for detecting an acceleration and outputting a signal indicating the acceleration, and a spacer located on the bottom part of the case. In addition, the sensor includes an amplifier circuit board attached to the case in the state of being opposed to the detection section with the spacer interposed therebetween and having an amplifier on a substrate thereof for amplifying the signal output by the detection section. Relay terminals are provided for electrically connecting the detection section and the amplifier circuit board, together with output terminals electrically connected to the amplifier circuit board for supplying the amplified signal to an external circuit. The detection section is surrounded by the case, the spacer and the amplifier circuit board. The case has projections used for attaching the acceleration sensor to the object.
