A connector includes a housing that allows a terminal lead-out and an electric wire lead-out to be drawn outward in a direction orthogonal to a connector insertion/removal direction, a shield shell, and a male screw member that secures the shield shell to a fixture base in a state where the connector mating is completed when the connector insertion/removal direction is defined as a screw axis, in which the shield shell includes a first shell and a second shell each of which having a through hole respectively that allows insertion of the male screw member and configured to sandwich the housing in the connector insertion/removal direction, and includes a first pressing plate and a second pressing plate that grip the terminal lead-out in the connector insertion/removal direction in the state where the connector mating is completed.
