Abstract
An acceleration sensor includes a circuit board having an acceleration signal output electrode and a ground electrode formed on its one major surface, a piezoelectric element fixed on the acceleration signal output electrode, a conductive member fixed on the ground electrode, and a weight member mounted in a crosslinked manner and fixed on the conductive member and the piezoelectric element, and wherein the piezoelectric element is so arranged that its axis of polarization is in a direction along the direction in which acceleration is applied, and the weight member is so constructed that its one surface in contact with the piezoelectric element and the conductive member has conductivity.
