An accelerometer is composed of a pair of housings each of which forms a magnetic structure together with a permanent magnet and a flapper flexurally supported by hinge portions between the magnetic structures. The permanent magnet is secured to the housing of the magnetic structure by means of a spacer so as to prevent a harmful thermal stress which will be caused by the difference of thermal expansion between the magnet and the housing. A bobbin with a torquer coil is secured to the flapper by means of a base member to take no effect of thermal stress which will be caused by the difference between the materials of the bobbin and the flapper. The above elements are housed in a case which is installed in an instrument board so as to be unaffected by changes in temperature in surroundings of the accelerometer.
