PROBLEM TO BE SOLVED: To provide an electronic clinical thermometer with a cover in which a body temperature can be measured accurately at all the time by preventing generation of thermal disturbance without increasing a burden upon a user when measuring the body temperature while using only one temperature measuring part, the electronic clinical thermometer comprising a plurality of temperature measuring parts including at least a contact type temperature measuring part.SOLUTION: An electronic clinical thermometer 100 with a cover in which at least a part of an electronic clinical thermometer 11 is covered with a cover member 13 comprises a plurality of temperature measuring parts 25, 31 disposed at positions different from each other in the electronic clinical thermometer 11 and including at least a contact type temperature measuring part, a control part which measures a body temperature while using only one of the plurality of temperature measuring parts, and the cover member 13 which covers the contact type temperature measuring part 25 that is not used for measuring the body temperature, during the measurement of the body temperature.【課題】接触式の測温部を少なくとも含む複数の測温部を備えた電子体温計で、いずれか一つの測温部のみ使用して体温測定を行う場合に、使用者への負担を増やすことなく熱的な外乱発生を防止でき、常に正確な体温測定が行えるカバー付き電子体温計を提供する。【解決手段】電子体温計11の少なくとも一部がカバー部材13により覆われるカバー付き電子体温計100であって、電子体温計11のそれぞれ異なる位置に配設され、接触式の測温部を少なくとも含む複数の測温部25,31と、複数の測温部のいずれか一つのみ使用して体温測定を行う制御部と、体温測定時に、体温測定に使用していない接触式の測温部25を覆うカバー部材13と、を備えた。【選択図】図4
