  According to this configuration, unlike the above-described prior art, the battery is arranged in a space different from the circuit board housed in the back cabinet, which is arranged on the back side of the metal plate. Thus, it becomes possible to accommodate a large battery. As a result, it is possible to provide a mobile terminal that can cope with high-speed processing.

  In the 1st portable terminal of this invention, the adhesive bond layer is provided in the front side surface of the battery accommodating part, and the battery may be affixed on the metal plate by the adhesive bond layer.

  According to this configuration, the battery can be provided in the battery housing portion with a simple configuration.

  In the 1st portable terminal of this invention, a double-sided tape may be sufficient as the adhesive bond layer provided in the front side surface of the battery accommodating part.

  The second portable terminal of the present invention is fitted into a front cabinet having a display recess on the front side, a back cabinet attached to the front cabinet, a metal plate integrally formed with the front cabinet, and a display recess. The display panel and a circuit board disposed on the back side of the metal plate and housed in the back side cabinet are provided. The metal plate is formed with a battery recess disposed on the back side of the display recess. It is fitted in the concave part for use, and is arranged between the display panel and the metal plate.

  According to this configuration, unlike the above-described prior art, the battery is arranged in a space different from the circuit board housed in the back cabinet, which is arranged on the back side of the metal plate. Thus, it becomes possible to accommodate a large battery. As a result, it is possible to provide a mobile terminal that can cope with high-speed processing.

  Further, since the periphery of the battery fitted in the battery recess can be surrounded by the metal plate, it is possible to suppress the external impact on the battery and suppress the deformation of the battery.

  In the portable terminal of the present invention, an adhesive layer may be provided on the front surface of the battery recess, and the battery may be attached to the metal plate with the adhesive layer.

  According to this configuration, the battery can be provided in the battery recess with a simple configuration.

  In the portable terminal of the present invention, the adhesive layer provided on the front surface of the battery recess may be a double-sided tape.

  In addition, the portable terminal of the present invention has an excellent characteristic that it can provide a portable terminal capable of accommodating high-speed processing by accommodating a large battery. Therefore, the present invention can be suitably used for a portable terminal whose display panel is a liquid crystal display panel or an organic EL display panel, and a portable terminal whose protective panel is a touch panel.

  ADVANTAGE OF THE INVENTION According to this invention, a large sized battery can be accommodated and the portable terminal which can respond to high-speed processing can be provided.
