Probe fitting structure and probe

A probe fitting structure comprising:

• a connector to be inspected, the connector including a plurality of connection electrodes;
• and
• a probe configured to fit to the connector, the probe including
• a flange having a through hole,
• a coaxial cable extending through the through hole and including a leading end portion to which at least one probe pin is attached,
• a plunger including a leading end through which the at least one probe pin is exposed, and at least one plunger-side fitting portion in a leading end portion of the plunger, and
• a spring housing the coaxial cable between the flange and the plunger and including a first end portion fixed to the flange and a second end portion fixed to the plunger, and
• the connector includes at least one connector-side fitting portion configured to fit to the at least one plunger-side fitting portion while surrounding the at least one plunger-side fitting portion.

A probe for inspecting a connector including a connection electrode, the probe comprising:

• a flange having a through hole;
• a coaxial cable extending through the through hole;
• a plunger having a planar base end portion;
• and
• a probe pin attached to the coaxial cable and including a leading end exposed from the base end portion,
• wherein the plunger includes a plurality of protruding portions between which the probe pin is disposed when the base end portion is seen in plan view, and
• a length from the base end portion to a leading end of each of the plurality of protruding portions is longer than a length from the base end portion to the leading end of the probe pin.
