US 2019/0100027 A1 · THERMAL HEAD AND THERMAL PRINTER

Abstract

A thermal head includes a substrate, a glaze layer, and a reinforced conductor layer. The glaze includes a first glaze and a second glaze. The first glaze extends in a predetermined direction on the surface of the substrate. The second glaze is spaced part from the first glaze to one side in a direction perpendicular to the predetermined direction on the surface of the substrate. The reinforced conductor layer includes a lateral side part. The lateral side part extends on the surface of the substrate from the first glaze side to the second glaze side and is partially located on the second glaze. An edge part on the first glaze side in the second glaze includes a cutout portion cut out toward the one side in the direction perpendicular to the predetermined direction. The lateral side part passes through the cutout portion.
