Abstract: Disclosed is a method of manufacturing an acceleration sensor including: a cylindrical body composed of a conductive material; a magnetized inertial body so charged in an interior of the cylindrical body as to be movable in the longitudinal direction of the cylindrical body; a conductive body provided on an end surface of at least one end of the magnetized inertial body in the longitudinal direction of the cylindrical body; a pair of electrodes disposed at one end in the longitudinal direction of the cylindrical body and made conductive through the conductive body when contacting the conductive body of the magnetized inertial body; and an attracting body composed of a magnetic material, disposed at the other end in the longitudinal direction of the cylindrical body and magnetically mutually attracting the magnetized inertial body, the method comprising the steps of: assembling the acceleration sensor by incorporating the inertial body before becoming the magnetized inertial body by magnetization; and magnetizing the inertial body by thereafter applying a magnetic field to this assembled unit.
