Ceramic structure and method manufacturing ceramic structure

A ceramic structure comprising:

• a base body which is made of ceramic and comprises a first surface;
• and
• an internal conductor which is located inside the base body and comprises a connection portion;
• and
• a terminal which is joined to the connection portion at an upper end surface of the terminal, wherein
• the base body comprises a space extending from the connection portion to the first surface,
• the internal conductor comprises a conductor layer which extends along the first surface over the space and an outer side of the space,
• the conductor layer having a second surface located on a side of the space and a third surface located on a side of the conductor layer opposite to the second surface and in contact with the base body,
• the conductor layer further comprises a part of the conductor layer overlapping the space, the part of the conductor layer including at least a portion of the second surface located on the side of the space and at least a portion of the third surface located on the side of the conductor layer opposite to the second surface, the at least a portion of the second surface and the at least a portion of the third surface of the part of the conductor layer flexing to a side closer to the first surface, and
• a bonding material is interposed between the part and the upper end surface.
