Abstract
An acceleration sensor for a pedometer has a base member which bends along one plane, a piezoelectric element which is set on and bends with this base member, and a weight member at one end portion of the base member. The weight member causes the base member and the piezoelectric element to be deformed when it is accelerated in whatever direction. A pedometer includes such an acceleration sensor and outputs from the acceleration sensor are processed by a control circuit and the number of steps taken by the user or the distance walked by the user can be displayed on a display device.

An acceleration sensor comprising:
- a base member which bends along one plane;
- and
- a piezoelectric element set on said base member, said piezoelectric element bending with said base member.
A pedometer comprising:
- an acceleration sensor having a base member which bends along one plane, a piezoelectric element set on said base member, and a weight member at one end portion of said base member, said piezoelectric element bending with said base member;
- a control circuit for processing signals outputted from said acceleration sensor and generating a pedometric output therefrom;
- and
- a display device for displaying said pedometric output generated by said control circuit.
