Abstract
A thermal printhead includes a substrate, a resistor layer formed on the substrate, an electrode layer formed on the substrate and electrically connected to the resistor layer, and an insulating layer. The electrode layer includes a first electrically conductive portion and a second electrically conductive portion spaced apart from each other. The resistor layer includes a heater portion that bridges the first electrically conductive portion and the second electrically conductive portion as viewed in the thickness direction of the substrate. The insulating layer includes a portion positioned between the electrode layer and the heater portion. This arrangement reduces formation of a eutectic region between the heater portion and the electrode layer.
