More Information
Summary:The object is to provide a thermal print head capable of improving printing quality on a medium. The Solution is to provide a base member 11 including a recess 113a, a heat storage region 2 formed in the recess 113a, a resistor layer 4 formed on the base member 11, and an electrode layer 3 formed on the base member 11 and electrically connected to the resistor layer 4. The resistor layer 4 includes a heating portion 41 spanned between two portions of the electrode layer 3 spaced from each other as viewed in a thickness direction Z of the base member 11. The heating portion 41 is located so as to overlap the recess 113a as viewed in the thickness direction Z. The base member 11 is made of a material having a thermal conductivity of 100 to 300 W/(m·K).
