PURPOSE: To provide an inexpensive sensor suitable for installation of printed wiring board by arranging a float above magnet and a magnetic-electric transducing element vertically and arranging an external lead terminal below the magnetic-electric transducing element vertically and supporting the rotary shaft of the magnet by a bearing receiving thrust load. CONSTITUTION: A float 21 is arranged above a magnet 3 and a magnetic-electric transducing element 4 vertically, while an external lead terminal 5 is arranged below the magnetic-electric transducing element 4 vertically. A rotary shaft 22 of the magnet 3 is supported by a bearing receiving thrust load 23. The whole of the float 21 is immersed in a liquid 8. For the float 21 made of a material, which is provided with elasticity slightly, such as light alloy and synthetic resin, a hollow or foam type one, which can maintain mechanical structure, is available, and the float 21 is provided with a specific gravity slightly smaller than that of the liquid 8 as the whole. By the float 21, rotation torque based on an inclination angleθis fed to the rotary shaft 22, and the direction of a pendulum depending on the float 21 can be maintained in the vertical direction.
