Abstract:
A thermal printhead includes a substrate, a protrusion formed on an obverse surface of the substrate and extending in a main scanning direction, a heat storage layer formed on a top surface of the protrusion, and a plurality of heat-generating parts arranged along the main scanning direction on the heat storage layer. The substrate and the protrusion are integrally formed from a single-crystal semiconductor.
