ABSTRACT:
An organic positive temperature coefficient (PTC) thermistor includes an organic PTC thermistor sheet on which a roughened surface is formed by pressing a wire mesh against one main surface thereof at a predetermined pressure. This results in the main surface of the organic PTC thermistor sheet being roughtened. A pair of electrodes are then formed on the main surface of the organic PTC thermistor sheet.
