PROBLEM TO BE SOLVED: To provide a device securing contact of a temperature sensor to the skin, and improving mountability by reducing discomfort and unpleasantness due to device attachment, with respect to a body temperature measuring device for measuring at least a skin temperature by mounting on the body.SOLUTION: A body temperature measuring device for measuring at least a skin temperature by mounting on clothing worn on the skin of a measurer is such that: a skin temperature sensor 15 is arranged in a prescribed position of a skin side case body surface 13 of a device body 12 to be a skin side of the measurer; a clip part 17 is openably/closably provided on a step surface 13A lower than the skin side case body surface 13 arranged with the skin temperature sensor 15; and the clip part 17 is put in a roughly planar state with the skin side case body surface 13 arranged with the skin temperature sensor 15 when pinching one end of the clothing by the clip part 17 and the step surface 13A.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】身体に装着させて少なくとも皮膚温度を測定する体温測定装置に関し、皮膚に対する温度センサの接触を確保し、装置装着による違和感や不快感を軽減させて装着性を向上させる装置を提供する。【解決手段】測定者の皮膚上に着用している衣類に装着させて少なくとも皮膚温度を測定するものであり、皮膚温度センサ15を測定者の皮膚側となる装置本体12の皮膚側筐体面13の所定位置に配置させ、クリップ部17を皮膚温度センサ15が配置されている皮膚側筐体面13より低い段差面13Aに開閉自在に設け、当該クリップ部17と段差面13Aとにより衣類の一端を挟持させた際に、当該クリップ部17が皮膚温度センサ15の配置されている皮膚側筐体面13と略平面状態とさせる構成とする。【選択図】図1
