Manufacturing method of heat-generating plate material, heat-generating plate material manufactured by the manufacturing method, plate-like structure, and heat-generating system

A manufacturing method of a heat-generating glass (100) that has a conductive thin film (120) formed on at least one surface of a translucent plate material (110). The conductive thin film (120) is energized for heat-generating when power is applied. A metal tape (132) is fixed on to the conductive thin film (120) formed on the plate material (110) along each of the opposing two sides of the plate material (110). A silver paste (134) is applied to the metal tape (132) from above so as to cover it. A heater section (220) of a heater (200) that is at least longer than the total length of the metal tape (132) is brought into contact with each of the edge parts forming two sides to which the metal tape (132) of the plate material (110) is fixed in a state where a temperature of the heater section (220) is a prescribed temperature or above to cure the silver paste (134). An electrode (130) comprising the metal tape (132) and the silver paste (134) is formed to be electrically connected to a lead wire (140).
