An object is to realize an ear thermometer that is configured to easily arrange a sensor in a sensor mirror and is suitable for mass production. The ear thermometer has a probe. The probe includes a probe body and a temperature measuring part joined with the probe body. The temperature measuring part includes a flange coupled with the probe body and a front end part extending from the flange, the front end part incorporating a sensor mirror. The sensor mirror includes a cylindrical holder with an internal concave reflection face, a connection shaft extending from the back of the cylindrical holder, a flexible printed circuit board with a circuit conductor of predetermined pattern, stretched in a front space of the cylindrical holder, a temperature measuring first sensor and a correcting second sensor spaced by a predetermined distance from each other in a longitudinal direction of the board and soldered to the circuit conductor on the board, and a protection cover covering a front face of the cylindrical holder. The board is electrically connected, in the temperature measuring part, to the cable passing through the probe body.

This infrared thermometer (1) includes: a main unit (1R) incorporating an infrared sensor (3); a proximity sensor (100) for detecting that the main unit (1R) has been positioned in proximity to a human body; and a controller (83) which calculates body temperature based on quantity of infrared from the infrared sensor (3) when the proximity sensor (100) has detected positioning of the main unit (1R) in proximity to a human body. The proximity sensor (100) includes a ground electrode (5), and a plurality of segmented electrodes (7, 7B, 7C, 7D) arranged about the perimeter of the ground electrode (5). The controller (83) measures electrostatic capacitance between the ground electrode (5) and the segmented electrodes (7, 7B, 7C, 7D) when positioned in proximity to a human body, and measures the distance between the main unit (1R) and the human body, to thereby detect tilt of the main unit (1R) with respect to the human body.
