PROBLEM TO BE SOLVED: To provide a tilt angle sensor capable of finely detecting continuous angle value of a vehicle and the like. SOLUTION: The fulcrum of a metal pendulum 13 is supported swingably in a case 11. In the vicinity of the pendulum 13, a magnetic force output coil 21 as a magnetic force output part whose magnetic force is arranged in a direction perpendicular to the swinging direction of the pendulum 13 outputs periodically varying magnetic force. The tilt sensor is constituted so that the magnetic force having varied through the pendulum 13 swinging corresponding to the angle value is output as an electromagnetic induction voltage by a magnetic force detection coil 22 arranged facing the magnetic force output coil 21.
