Claims

[Scope of utility model registration request]

an infrared detector that generates an electric charge according to the amount of change in incident infrared rays; a pair of opposing bodies having a number of infrared passing parts and infrared non-passing parts and located in the infrared incident area of the infrared detector; The opening/closing degree of the infrared passing section of the opposing body is periodically changed. An infrared sensor characterized in that the infrared sensor is adhesively fixed to a non-vertical surface of the vibrating body that is not perpendicular to the vibration direction of the vibrating body using an adhesive stored in a recess formed in the non-vertical surface.
