徴とする加速度センサ。[Claims for Utility Model Registration] A cylindrical bobbin disposed with its axis directed in the vertical direction, a magnetic body housed within the bobbin, a housing disposed outside the bobbin, and the above-mentioned body fixed to the housing. A magnet that attracts the magnetic material to a reference position in the axial direction within the bobbin, and a detection means attached to the outer periphery of the bobbin to detect displacement of the magnetic material from the reference position, the bobbin having a higher coefficient of thermal expansion than the housing. What is claimed is: 1. An acceleration sensor made of a material having a large diameter, wherein the upper end of the bobbin is cantilever-supported by the housing, and the lower end of the bobbin is a free end.
