The movable housing has an entry wall portion that enters the interior space of the stationary housing; terminal holding grooves accommodating a portion of the resilient portions, which extend in the direction of connection to a counterpart connect body, are formed to be arranged in the terminal array direction on one wall surface of the entry wall portion; movable-side terminal holding portions securing the movable-side retained portions of the terminals are formed on the opposite side in the connector width direction perpendicular to said one wall surface; between adjacent terminal holding grooves. When the terminals are attached in the direction of connection from the circuit board side, the projections have gaps formed between them and the resilient portions of the terminals located within the terminal holding grooves in the terminal array direction.
