Claim Text:
1. A thermal printhead comprising: 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; wherein 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 a thickness direction of the substrate, the insulating layer includes an intervening portion positioned between the electrode layer and the heater portion in the thickness direction of the substrate, and the first electrically conductive portion and the second electrically conductive portion are connected to the resistor layer via a plurality of openings formed in the intervening portion of the insulating layer.
