Abstract (en)
[origin: EP0429002A2] A thermal recording head includes a pair of electrode fine wires (10, 20) and a resistance heating element (50). A peripheral surface of each electrically conductive core (30) of the fine wires is covered with an insulating layer (40). Each electrode fine wire in the pair of fine wires is arranged to form each line while end surfaces of the pair of fine wires confront each other through a space. Instead, the pair of fine wires are arranged to form a line while end surfaces of the pair of fine wires are lined up with each other. The element is electrically connected the cores exposed at the end surfaces of the pair of fine wires with each other to apply a signal current to the pair of fine wires, and generates heat in correspondence with the current.
