Abstract
An infrared thermometer for measuring a body temperature in no contact with a human body includes: a main unit incorporating an infrared sensor; a distance sensor detecting a distance between the main unit and the human body when the main unit approaches the human body; and a controller for calculating the body temperature based on quantity of infrared from the infrared sensor when the distance sensor detects that the distance between the main unit and the human body is within a predetermined distance. The distance sensor includes: a light source; a projector lens for projecting light of the light source toward the human body; a light receiving sensor; and a light receiving lens that allows the light receiving sensor to receive return light of the light, which is obtained as a result of being reflected by the human body, when the main unit is located within the predetermined distance.
