Claim 0:
1. An electrode-embedded member comprising:
a ceramic-made substrate;
an electrode embedded in the substrate;
a connection member containing at least one of tungsten and molybdenum and having a first principal surface, a second principal surface, a side surface that connects the first principal surface to the second principal surface, and an edge formed by the second principal surface and the side surface along an entire circumference of the second principal surface, the connection member being embedded in the substrate in a state in which the first principal surface faces the electrode and the connection member is electrically connected to the electrode; and
a hole portion extending from an outer surface of the substrate to the second principal surface of the connection member,
the electrode-embedded member being characterized in that
a buffer member is embedded in the substrate,
the buffer member contains at least a ceramic material and at least one of tungsten and molybdenum, and
the buffer member covers at least part of the edge of the connection member.
