MEDICAL HEATER, TREATMENT INSTRUMENT, AND METHOD FOR MANUFACTURING TREATMENT INSTRUMENT

摘要

A medical heater 13 is provided with: a substrate 14 having first and second plate surfaces 14a, 14b which have electrical insulating properties and are flexible, and which form a front and rear with each other; and an electroconductive part 15 provided on the first plate surface 14a. The electroconductive part 15 is provided with: a pair of connection parts 151, 152, to each of which a wiring member C1 is electrically connected, and which are provided to both longitudinal end parts of the substrate 14; a heating part 153 for generating heat in response to energization thereof; and an electrical path part 154 for energizing the heating part 153, the electrical path part 154 being connected from the connection parts 151, 152 to the heating part 153. The heating part 153 is configured so that the resistance value of the heating part 153 is higher than the resistance value of the other sections of the electroconductive part 15, and the thickness dimension of at least a portion of the heating part 153 is smaller than the thickness dimension of the other sections of the electroconductive part 15.
