Thus, the locking portion 82 of the FPC 80 engages with the convex portion 56 of the housing 12. That is, when the FPC 80 is inserted, the FPC 80 can be inserted without applying an insertion force. By rotating the rotating member 16, the rotating member 16 elastically deforms the contact 14, and the upper side of the contact 14 is changed. By pressing down the FPC 80 at the same time when the one contact portion 22 contacts the contact point of the FPC 80, the locking portion 82 of the FPC 80 is engaged with the convex portion 56 of the housing 12, and the FPC 80 can be held by being engaged. .

  As an application example of the present invention, it is used for a connector 10 used in an electric device or an electronic device such as a mobile phone, a notebook computer, or a digital camera, and in particular, a separate flexible printed circuit board (without using a separate member) (Hereinafter referred to as “FPC”).
