A floating connector used in a state where the floating connector is mounted on a circuit board, the floating connector being mateable with and removable from a mating connector along an up-down direction, wherein: the mating connector has a mating contact portion; the floating connector comprises a movable housing, a plurality of contacts and at least one ground member; the movable housing has a first holding portion and a second holding portion; each of the contacts has a fixed portion, a first held portion, a coupling portion, an extending portion and a contact portion; the fixed portion is fixed to the circuit board when the floating connector is mounted on the circuit board; the first held portion is held by the first holding portion; the coupling portion couples the fixed portion and the first held portion with each other; the coupling portion is resiliently deformable; the movable housing is movable within a predetermined range in a plane perpendicular to the up-down direction by the resilient deformation; the extending portion extends upward in the up-down direction from the first held portion; the contact portion is brought into contact with the mating contact portion when the floating connector is mated with the mating connector; the contact portion is supported by the extending portion; the contacts include a plurality of ground contacts and a signal contact; the ground member has a plurality of ground contact portions, a plurality of supporting portions, a ground coupling portion and a second held portion; the ground contact portions correspond to the ground contacts, respectively; each of the ground contact portions is brought into contact with the corresponding ground contact even when the movable housing is moved within the predetermined range; the supporting portions support the ground contact portions, respectively; the ground coupling portion couples the supporting portions with each other; and the second held portion is held by the second holding portion, characterized in that each of the supporting portions is bent from the ground coupling portion to extend outward in a width direction perpendicular to the up-down direction, and is then bent to extend upward in the up-down direction; each of the supporting portions is resiliently deformable independently of each other. the mating connector has a mating contact portion; the floating connector comprises a movable housing, a plurality of contacts and at least one ground member; the movable housing has a first holding portion and a second holding portion; each of the contacts has a fixed portion, a first held portion, a coupling portion, an extending portion and a contact portion; the fixed portion is fixed to the circuit board when the floating connector is mounted on the circuit board; the first held portion is held by the first holding portion; the coupling portion couples the fixed portion and the first held portion with each other; the coupling portion is resiliently deformable; the movable housing is movable within a predetermined range in a plane perpendicular to the up-down direction by the resilient deformation; the extending portion extends upward in the up-down direction from the first held portion; the contact portion is brought into contact with the mating contact portion when the floating connector is mated with the mating connector; the contact portion is supported by the extending portion; the contacts include a plurality of ground contacts and a signal contact; the ground member has a plurality of ground contact portions, a plurality of supporting portions, a ground coupling portion and a second held portion; the ground contact portions correspond to the ground contacts, respectively; each of the ground contact portions is brought into contact with the corresponding ground contact even when the movable housing is moved within the predetermined range; the supporting portions support the ground contact portions, respectively; the ground coupling portion couples the supporting portions with each other; and the second held portion is held by the second holding portion, characterized in that each of the supporting portions is bent from the ground coupling portion to extend outward in a width direction perpendicular to the up-down direction, and is then bent to extend upward in the up-down direction; each of the supporting portions is resiliently deformable independently of each other.
