Disclosed is a thermal cutting blade of a self-heating type for melting and cutting a resin tube, comprising a ceramic substrate (2), a resistor element (3) formed on the ceramic substrate in a desired pattern, for generating heat upon power supply, terminal portions (4, 5) formed on both ends of the resistor element, and an insulating layer (6) covering the surface of the resistor element. The thermal cutting blade is excellent in thermal properties, thin due to a simple structure, and is manufactured readily at a low cost. <IMAGE> |
