A connector comprises a housing, a contact and a connection structure. The connection structure is a structure other than the housing and comprises a conductive member, a protection portion and an electric-shock prevention portion. The conductive member has a first end portion and a second end portion. The first end portion is attached to or integrally formed with the contact. The protection portion covers a part of the conductive member, which is positioned between the first end portion and the second end portion. The housing has an accommodation portion formed therewithin. The accommodation portion has an opening. The contact is accommodated in the accommodation portion together with the first end portion of the conductive member. The electric-shock prevention portion, at least in part, blocks the opening of the accommodation portion and obstructs entrance of a finger into the accommodation portion beyond the electric-shock prevention portion.
