PROBLEM TO BE SOLVED: To enable a setting of a gap for regulating oscillation of a mass part of a pendulum to be performed without adjustment, and make eliminable a mechanical adverse effect to a hinge part. SOLUTION: In the accelerometer, mount plates 29a and 29b including a pair of permanent magnets 25 form a magnet assembly 20, and a pendulum 14 is set by screws 24a and 24b to a stand 23 and integrally constructed with a base 22. A torquer coil 18 and a slit plate 19 are provided to a mass part 13 of the pendulum 14 to respond to a direction of an external acceleration and, a pair of projection parts 13d are set to both sides of the mass part. A pair of stoppers 32 and a pair of stoppers 31 are respectively set to the mount plate 29a and the stand 23 corresponding to the projection parts 13d so as to regulate oscillation of the pendulum 14. A gap between the projection part 13d and stopper 32, and a gap between the projection part 13d and stopper 31 are set to be an optimum size from a view point of design.
