Abstract: An infrared temperature sensor that detects temperature of a detection object in a non-contact manner includes a sensor case that includes a light guiding region and a light shielded region, a film that absorbs and converts infrared rays into heat, a sensor cover, an infrared detection element, and a temperature compensation element. The sensor case includes a case base portion and a hood that surrounds the light guiding region and the light shielded region and is erected from the case base portion. The hood includes an opening part and a shielding part that protrudes toward an inside of the hood while defining the opening part and the light guiding region, and shields the light shielded region from the infrared rays. A protrusion direction of the shielding part toward the inside of the hood is adjustable.

Abstract: An infrared temperature sensor includes a sensor case, a heat conversion film configured to absorb infrared rays and to convert the infrared rays into heat, a sensor cover that is disposed to face the sensor case through the heat conversion film, and an infrared detection element and a temperature compensation element that are disposed on the heat conversion film. The sensor case includes a case base portion that includes a front surface and a rear surface, a light guiding region that is provided to penetrate through the front surface and the rear surface of the case base portion, and a light shielded region that is provided inside a light shielding dome erected from the front surface side of the case base portion.
