Abstract:
    A spring member (21) used in an acceleration sensor, for supporting weight members (22a-22d) that cooperate as magnetic field generation members or magnetic field detection sensors includes at least one strip-shaped plate spring (21b,21c) with a fulcrum and support sections (21d-21g) separated from the fulcrum for supporting the weight members (22a-22d). The at least one strip-shaped plate spring (21b,21c) is configured to produce a bending stress in response to an external force applied so as to displace the weight members (22a-22d).
