The method of forming is useful.

  In the flexible printed circuit board described in Patent Document 4, the rigidity of the entire flexible printed circuit board is certainly increased. Therefore, when the flexible printed circuit board is sandwiched from both sides by the contact pair, a sufficient contact pressure can be obtained. As a result of the deterioration of the specific flexibility, there is a problem that it is difficult to use in a usage mode in which it is used in a bent deformation state.

  Patent Document 5 already proposed by the present applicant uses an FPC that has contacts on both front and back surfaces, and has sufficient flexibility when sandwiched from both sides by a contact pair constituting a connector.
