A connector including a shell, an inner body inside the shell, a terminal held by the inner body and disposed inside the shell, a ground terminal, and an outer body. The outer body includes a generally tubular first portion extending in a first direction, a second portion, and an accommodation space in the first and second portions securely accommodating the shell. The second portion is larger than the first portion in outer cross-sectional dimensions and/or wall thickness in the second direction orthogonal to the first direction. The second portion has a hole extending from an outer face of the second portion to the accommodation space. The ground terminal is in contact with, or contiguous with, the shell and is disposed in the hole of the outer body. The ground terminal includes a portion exposed from the outer body or partly located outside the outer body.
