A tilt sensor includes: a rotating member in a nearly U-shape having a weight part and a magnet part; a case main body which houses the rotating member in an interior space; and a single magnetic field detecting member having a single magnetic flux detecting area on a circumference of a rotating shaft of the rotating member, wherein the case main body is tilted to relatively rotate the magnet part, and the magnetic field detecting member detects a tilt state of the case main body, wherein the rotating shaft of the rotating member is disposed at the center of the interior space of the case main body, and multiple magnet parts are independently disposed on the circumference of the rotating shaft of the rotating member. The magnet parts are formed so that both ends of the rotating member formed of a magnetic substance are polarized. |
