<;P>;PROBLEM TO BE SOLVED: To massively produce ear thermometers by providing a structure for easily installing a sensor in a sensor mirror in the ear thermometer. <;P>;SOLUTION: A probe includes a body part and a temperature measuring part connected to a body part. The temperature measuring part includes a flange part connected to the body part and a front end extending from the flange part. The sensor mirror is fitted inside the front end. The sensor mirror includes a cylindrical holder having a concave reflecting surface on the inside, a connecting shaft extending from the rear part of the cylindrical holder, a flexible printed circuit board having a circuit conductor of a predetermine pattern and stretched across the front space of the cylindrical holder, a first sensor for the temperature measurement and a second sensor for the correction soldered to the circuit conductor on the board with their spaced a predetermine interval in the longitudinal direction of the board, and a protection cover for covering the front face of the cylindrical holder. The board is electrically connected to a cable penetrating through the body part in the temperature measuring part. <;P>;COPYRIGHT: (C)2009,JPO&INPIT
