The portion 604 is inserted and fitted inside the cylinder of the cylindrical portion 604a.

  In FIG. 11A, the cylindrical portion 603a of the hinge portion 603 is inserted and fitted between the upper left edge 103p of the lower housing 103 and the protruding cylindrical portion 103r, and the leg portion 603b of the hinge portion 603 has the upper The screw 113 is inserted and fitted into the inside of the second housing part 102b, the screw 113 is inserted into the circular hole 603h, and screwed by the screw 113. The cylindrical portion 604a of the hinge portion 604 is inserted and fitted between the upper right edge 103q of the lower housing 103 and the protruding cylindrical portion 103r, and the leg portion 604b of the hinge portion 604 is connected to the upper second housing portion 102b. The screw 114 is inserted into the circular hole 604h and screwed by the screw 114. A connection point 111 of the wireless communication circuit 110 is connected to the fitting cylindrical member 606 via an antenna element 605 provided to extend inside the lower housing 103, and a connection point 609 of the wireless communication circuit 110 is connected to the lower housing 103. It is connected to the fitting cylindrical member 608 via an antenna element 607 provided to extend inside the body 103.

  In the portable wireless communication device configured as described above, the connection point 111 of the wireless communication circuit 110 is connected to the upper first housing portion 102a via the antenna element 605, the fitting cylindrical member 606, the hinge 603, and the screw 113. The connection point 609 of the wireless communication circuit 110 is electrically connected to the upper first housing 102a via the antenna element 607, the fitting cylindrical member 608, the hinge 604, and the screw 114. I have. Here, a circuit from the antenna element 605 to the upper first housing part 102a and a circuit from the antenna element 607 to the upper first housing part 120a constitute a first antenna element 102A.
