Abstract
A thermal printhead includes a substrate, a resistor layer with heat generation portions supported by the substrate and aligned in a primary scanning direction, a wiring layer supported by the substrate to form a conductive path to the heat generation portions, an insulating layer interposed between the substrate and the resistor layer, and a reflection layer located opposite to the heat generation portions with respect to the insulating layer. The reflection layer overlaps with the heat generation portions as viewed in a thickness direction of the heat generation portions and has a greater heat reflectivity than the insulating layer.
