Document Type and Number:
WIPO Patent Application WO/2019/207807
Kind Code:
A1
Abstract:
This treatment tool includes: a heat exchanger plate 13 that has a first surface and a second surface 132 provided on mutually opposite sides; a heater 15 that has an electrically insulating substrate 16, and an electrical resistance pattern 17 that is formed on, and widthwise inward of, the substrate 16 and generates heat when electric current is passed therethrough; and an electrically insulating adhesive member 14 that is disposed in an adhesive region Ar on the second surface 132 and adheres the heat exchanger plate 13 to the heater 15. The substrate 16 and the adhesive member 14 each has a long shape that extends from a distal end to a base end of the adhesive region Ar. The substrate 16 has a smaller width dimension in the adhesive region Ar than the adhesive member 14. The heat exchanger plate 13 is at a predetermined angle to the second surface 132, and further has an abutting surface 133a to which a widthwise end of the adhesive member 14 and a widthwise end of the substrate 16 abut.
