A hemispherical space 9 into which the spherical base end 3B of the temperature measuring unit 3 is rotatably fitted is formed in the main body 6. With this configuration, while the spherical outer peripheral surface of the base end portion 3B and the peripheral surface of the hemispherical space 9 of the main body portion 6 are in contact with each other, the distal end portion 3A contacts the edge of the hemispherical space 9 of the main body portion 6.

量に対応した鼓膜温度を正確に測定することができる。FIG. 3 shows a state in which the temperature measuring unit 3 of the thermometer 1 is inserted into the ear hole B. Even if the angle when holding the main body 6 is not constant, as shown in FIG.
Since the angle A changes along the ear hole B, when the temperature measuring unit 3 is inserted into the ear hole B, the angle of the sensor 2 with respect to the eardrum A becomes constant. Therefore, the sensor 2 has a constant receiving angle of infrared rays emitted from the eardrum A, and can accurately measure the eardrum temperature corresponding to the amount of infrared rays from the eardrum A.

Will be described. FIG. 5 shows that an adapter 10 that fits the inner diameter of the ear hole B is attached to the outer periphery of the distal end portion 3A of the temperature measuring unit 3 when the inner diameter of the ear hole B is too large compared to the outer diameter of the distal end portion 3A of the temperature measuring unit 3.

By attaching the adapter 10, the gap with the ear hole B can be almost eliminated. Therefore, even if the inner diameter of the ear hole B is larger than the outer diameter of the distal end portion 3A of the temperature measuring section 3, the angle of the sensor 2 with respect to the eardrum A is constant as shown in FIG. Therefore, the infrared light receiving angle of the sensor 2 becomes constant, and the body temperature corresponding to the amount of infrared light from the eardrum A can be accurately measured. Although the adapter 10 is shown to be used when the inner diameter of the ear hole B is larger than the outer diameter of the distal end portion 3A of the temperature measuring unit 3, the sensor 2 for the eardrum A is not used because the shape of the ear hole B is not linear. If the angle is not constant, the angle of the sensor 2 with respect to the eardrum A can be fixed using an adapter corresponding to the shape of the ear hole B.
