ABSTRACT:
A method of assembling a cylindrical heater whereby the cylindrical heater includes a positive temperature coefficient thermistor element sandwiched between a pair of terminal members at its opposite electrode surfaces. The thermistor element is inserted into an opening formed in a cylindrical case of a material having heat-shrinkability and thereafter, the cylindrical case is caused to shrink by heating for holding the positive temperature coefficient thermistor element and the terminal members under pressure so as to obtain thermal connection thereof.
