AI summary

A second component (electronic component) includes a second housing, an inner conductor, an outer conductor, and an internal shell. The second housing forms the storage space together with the first housing by being attached to the first housing. The outer conductor has a cylindrical shape and annularly surrounds the inner conductor and extends in the first direction. The internal shell is disposed inside the storage space and electrically connected to the outer conductor. The internal shell has a spring piece that makes elastic contact with the outer conductor.
