Patent ID: 11945051

Abstract:
A heater-sensor complex 10 includes a heating wire 12, a lead wire 14 which is made from the same metal of the heating wire 12 and connected to the proximal end of the heating wire 12, the lead wire 14 having a bigger diameter than the heating wire 12, a non-heating wire 16 constituted by a different metal from the metal constituting the heating wire 12, and a sensor head 18 constituted by a metal different from the metal constituting the heating wire 12 or the metal constituting the non-heating wire 16. The sensor head 18 have a lower thermal conductivity than the non-heating wire. To the sensor head 18, the distal end of the heating wire 12 and the distal end of the non-heating wire is connected. The heating wire 12 and the non-heating wire 16 electrically conducts at least through the sensor head 18.
