Electronic clinical thermometer and method of producing the same

A method of producing an electronic clinical thermometer that comprises a temperature-sensitive element, lead wire that is connected to the temperature-sensitive element, a body case having a probe part in which an insertion path for the lead wire to be inserted is formed, and a sensor cap having a cavity one end of which is opened to the body and the other end is closed, both the lead wire projecting from the insertion path and the temperature-sensitive element being stored within the sensor cap, the method comprising:

• mounting the sensor cap on the probe part, in a state where the lead wire having the temperature-sensitive element mounted on the tip thereof projects from the insertion path of the probe part, said mounting the sensor cap on the probe part comprises the steps of:
• setting a projecting length of the lead wire so that the projecting length is longer than a distance between a tip of the probe part and a tip of an inner wall of the cavity, when the sensor cap is mounted on the probe part and
• applying a pressing force to the sensor cap to cause the temperature-sensitive element to rotate which causes the lead wire, which is straight, to deform in proximity to the temperature-sensitive element by buckling so that the lead wire in deformed state comes into contact with an inner wall of the cavity near the temperature-sensitive element.
