The daughter board is inserted between upper and lower contact portions of the contact terminals with a zero-insertion force and then rotated to bring the pads into contact with the contact portions with a predetermined contact force, with the spring sections flexed so as to reduce the distance between the upper and lower contact portions and made floating.
