Abstract
The object is to provide a thermal print head capable of improving printing quality on a medium. The Solution is to provide a base memberincluding a recess, a heat storage regionformed in the recess, a resistor layerformed on the base member, and an electrode layerformed on the base memberand electrically connected to the resistor layer. The resistor layerincludes a heating portionspanned between two portions of the electrode layerspaced from each other as viewed in a thickness direction Z of the base member. The heating portionis located so as to overlap the recessas viewed in the thickness direction Z. The base memberis made of a material having a thermal conductivity of 100 to 300 W/(m·K).
