Abstract
A high-precision acceleration sensor capable of performing sensitivity adjustment by the sensor alone includes an acceleration sensing device disposed in an insulated case, in which external lead electrodes connected to the acceleration sensing device, a trimmable resistor, and external lead electrodes connected to both ends of the trimmable resistor, are formed on a surface of the insulating case. The trimmable resistor is a film-formed resistor made by printing. The sensitivity of the acceleration sensor can be adjusted by laser-trimming of the trimmable resistor.
