PURPOSE: A contactless temperature sensor is provided to prevent the temperature detection at an unnecessary domain. CONSTITUTION: A contactless temperature sensor comprises a case(100), a PCB substrate, a lends module(500), an infrared sensor chip and an operation part. The PCB substrate is arranged in the case and forms a light-receiving region. The infrared ray from a temperature detection object(P) is guided to the light-receiving region. A temperature detection object is protruded on the front face of the case. The infrared sensor chip is installed in a light-receiving region in order to receive infrared ray. The infrared sensor chip receives infrared ray and changes the ray into an electric signal. The operation unit is applied the electric signal of the infrared sensor chip and generates the temperature value.
