Abstract
A thermal head has a support substrate, an upper substrate arranged on the support substrate on one surface side thereof in a laminated state, and an intermediate layer arranged between the upper substrate and the support substrate to bond the upper substrate and the support substrate to each other. The intermediate layer has one of a through hole and a concave portion forming a cavity portion between the upper substrate and the support substrate. A heat generating resistor is formed on a surface of the upper substrate on a side opposite to the support substrate at a position opposed to the cavity portion. The intermediate layer is formed of a glass paste having a melting point lower than a firing temperature of the support substrate and higher than a melting temperature of the upper substrate.
