Patent attributes
A thermal printhead (A1) includes a substrate (1) and a plurality of heat-producing resistance sections (30) provided on the substrate (1). The heat-producing resistance sections (30) melt ink of an ink ribbon, which is transferred together with a recording sheet, to transfer the ink onto the recording sheet. An inequality surface region (7) is provided downstream from the heat-producing resistance sections (30) in a secondary scanning direction (x) which is the transfer direction of the ink ribbon. The inequality surface region includes a plurality of projections (70) each of which extends in the secondary scanning direction (x) and which are aligned at predetermined intervals in a primary scanning direction (y) which is perpendicular to the secondary scanning direction (x).
