Abstract
Abstract There is proposed a tilt sensor in which a permanent magnet (4) having a surface coated with a magnetic fluid (5) is housed in a space (3) inside a nonmagnetic case (1) and is freely movable, and a magnetic sensing element (6) is disposed to oppose the space through the case. When the case is tilted, the permanent magnet inside the space is moved to a lower position, and hence magnetism detected by the magnetic sensing element changes, thereby detecting a tilt of the case.
