The plurality of holes 14c formed in the key frame 40B are arranged so that convex portions 14d formed in the key sheet 40C described later are fitted. The input operation key member 14b is bonded to the convex portion 14d.

The hole 14c is formed so as to be larger than the outer periphery of the convex portion 14d and smaller than the outer periphery of the input operation key member 14b. Since the hole portion 14c is formed in this way, the outer periphery of the input operation key member 14b is placed on the lattice portion 14e formed around the hole portion 14c.
When the pressing surface of the input operation key member 14b is pressed, the pressing surface is bent and the outer periphery placed on the lattice portion 14e is supported by the lattice portion 14e. That is, the key frame 40 </ b> B can obtain the deformation necessary for the key operation and can suppress the excessive pressure applied to the circuit board 70.

  When the pressing surface of the input operation key member 14b joined to the convex portion 14d is pressed, the central portion of the pressing surface is bent. Thereby, the convex portion 14d is also deformed in the pressing direction. By this deformation, the key switch 52 arranged in the pressing direction of the convex portion 14d described later is in a connected state.

By doing in this way, the several antenna which has a different function can be formed with one member. Thereby, an increase in the number of parts and an increase in the number of assembly steps can be suppressed, and the mobile phone 1 can be reduced in size and thickness.

  Further, in the present embodiment, a spring connector having a spring and a terminal portion accommodated in the container portion and configured so that the terminal portion can be protruded and pushed in is used as the power supply terminal, but is not limited thereto. Any member having a predetermined elasticity may be used. For example, an elastic member or the like in which a plate-like metal member is bent to generate elasticity can be exemplified.

The external appearance perspective view in the state where cellular phone 1 was opened is shown. FIG. 6 is an exploded perspective view of members built in the operation unit side body 2. FIG. 5 is an exploded perspective view of members built in the display unit side body 3. 2 is a block diagram illustrating a configuration of a mobile phone 1. FIG. The perspective view explaining other embodiment in an antenna part is shown.
