A thermal print head including a glass layer disposed at the edge of a heat resistant substrate, a heat generating element on the glass layer and an electrode for driving the heat generating element disposed both under the glass layer and on the heat generating element is provided. The glass layer is formed of a lower layer of crystallized glass on the electrode and an upper noncrystallized glass portion under the heat generating element. The electrode under the glass layer is formed by print burning a thick conductive film on the substrate from a metal paste having a higher burning temperature than the burning temperature of the glass layers.
