摘要:
A thermal head including: a laminated substrate including a support substrate and an upper substrate at least one of which has a recess formed in a surface thereof; a heat generating resistor formed on a surface of the upper substrate in the laminated substrate at a position opposed to the recess; and a pair of electrode portions connected to each of both ends of a heat generating resistor, wherein the laminated substrate further includes: an intermediate metal layer sandwiched between the support substrate and the upper substrate and bonded thereto in a laminated state; and a surrounding metal layer formed of a metal material, the surrounding metal layer provided in contact with the intermediate metal layer and formed from a surface of the support substrate extending in a thickness direction thereof to a surface thereof opposite to a portion bonded to the upper substrate.
