An electrical connector with terminals having contact portions that come into contact with a connected circuit board and a housing that supports the terminals. The housing has a stationary housing for attaching to a circuit board and a movable housing configured to move with respect to the stationary housing. The connecting circuit board contacts the contact portions on the movable housing side. The terminals each have a stationary-side supported portion that is supported by the stationary housing, a movable-side supported portion that is supported by the movable housing, and an elastic portion that links the stationary-side supported portion and the movable-side supported portion. The elastic portions each have longitudinal portions extending in the connector mating direction, and a lateral portion extending in a direction perpendicular to the mating direction, and reach the stationary-side supported portions via bent portions that are bent at the inner ends of the lateral portions.
