Abstract
A thermal head has a support substrate that has a concave portion having an opening portion formed in a surface of the support substrate, and an upper substrate bonded to the surface of the support substrate in a stacked state to close the opening portion. The upper substrate has an external dimension which is smaller than an external dimension of the support substrate and is slightly larger than an external dimension of the opening portion for closing the opening portion. A heating resistor is formed on a surface of the upper substrate in a position opposed to the concave portion of the support substrate. The thermal head is high in durability and reliability with increased printing efficiency as well as increased manufacturing yields.
