An inorganic insulation layer is formed over a part of the thin-film thermal resistor and the thin-film conductor. An organic insulation layer is formed over at least a part of the inorganic insulation layer that covers the connecting edge of the connection portion between the thin-film thermal resistor and the thin-film conductor.
