A connector includes: a rod-shaped terminal; and a housing having a terminal accommodating chamber configured to accommodate the terminal. The terminal has: a rotation restricting portion configured to engage with an inner wall of the terminal accommodating chamber to restrict rotation of the terminal about an axis of the terminal; a contact configured to be electrically connected to a counterpart terminal; and a hole configured to allow a bolt to be screwed into the hole about the axis. The housing has: a holding portion that holds the terminal inside the terminal accommodating chamber; and an opening configured to expose the hole of the terminal to an outside of the terminal accommodating chamber. The connector is configured to have a gap between the inner wall of the terminal accommodating chamber and the terminal, the gap increasing from the rotation restricting portion of the terminal toward the opening of the housing.
