ABSTRACT:
A joining structure joining a ceramic substrate having a metal member buried therein and a power supply connector which supplies power to the metal member is provided. The joining structure includes a counterbore, a stress relaxation insert member, and a brazing member. The counterbore is formed in the ceramic substrate having a large-diameter part and a small-diameter part formed at a bottom center portion of the large-diameter part. At least a part of the metal member is exposed from a bottom of the small-diameter part. The stress relaxation insert member has a body part and a protrusion and is provided in the counterbore so that the body part and the protrusion are fitted into the large-diameter part and the small-diameter part, respectively. The brazing member connects the power supply connector to the stress relaxation insert member, and seals a gap between the counterbore and the stress relaxation insert member.
