1. A mobile instrument comprising:
- two housings that each incorporate circuit substrates;
a hinge portion that joins the two housings such that they can rotate; and
a flexible printed wiring board that is passed through a cavity formed inside the hinge portion, and that electrically connects together the circuit substrates in the two housings, whereinthe flexible printed wiring board is curled inside the cavity and an elastic body is placed on an inner side of the curled flexible printed wiring board wherein a transverse cross-sectional configuration of the elastic body and a transverse cross-sectional configuration of the cavity are substantially circular, and a diameter of the elastic body is equivalent to or greater than a diameter of the cavity.
