PURPOSE:To contrive higher printing quality, by providing heat generating resistors on a major surface of a substrate along one side edge of the substrate, and performing thermal recording on a side end surface orthogonal to the major surface on the side of the heat generating resistors. CONSTITUTION:A joint part between a heat generating resistor 2 and an electrode 9 is provided by connecting only in one direction on the side of a driving circuit part 3 so as to cover side faces of both end parts 2a of the resistor 2 provided in a split form. A side end surface 1c of a base substrate 1 is smoothly ground on the side of the heat generating resistors 2 provided between the substrate 1 and a protective substrate 5. With the ground side end surface 1c as a recording surface 6, a thermal head is disposed perpendicularly to a platen 7, in the same manner as in the case of an end face type thermal head, and is pressed against the platen 7 with a thermal recording paper S disposed therebetween, whereby thermal recording is conducted. Since the thermal head is disposed perpendicularly to the paper 8, contact characteristics are very good, and excellent printing quality is obtained. |
