The substrate is made of a single crystal semiconductor and includes an obverse surface facing in one sense of a thickness direction. The resistive layer is supported by the substrate and includes a plurality of heat generating parts arranged side by side in a main scanning direction. The wiring layer is supported by the substrate and forms a conductive path to the plurality of heat generating parts. The wiring layer includes a conductive part and a heat generating sub-part for each of the plurality of heat generating parts, where the conductive part has a lower resistance value per unit length in a sub-scanning direction than the heat generating part, and where the heat generating sub-part has a resistance value per unit length in the sub-scanning direction that falls between the respective resistance values of the heat generating part and the conductive part. The substrate includes a ridge raised from the obverse surface and extending in the main scanning direction. The heat generating part, the heat generating sub-part and the conductive part are disposed on the ridge. The heat generating sub-part is located between the heat generating part and the conductive part in the sub-scanning direction.

摘要： The present invention provides a recording head for a photographic printing device. The recording head of the present invention includes on a substrate two heating elements arranged adjacently and parallel to each other on a substrate. Each of the heating elements has connected to its ends a connection section, the connection sections and the heating element lying in a straight line. First and second connection sections are connected to the first heating element and third and fourth connection sections are connected to the second heating element. The heat capacities of the first and fourth connection sections are different from that of the second and of the third connection sections. The heat capacities of the first and fourth connection sections are substantially the same, as are the heat capacities of the second and third connection sections.
