- the portable terminal of the present invention is characterized in that, in the above-described configuration, the portable terminal includes a metal plate extending between the rechargeable battery and the circuit board so as to extend to the outer peripheral side of the circuit board.
- the heat generated from the electronic component is conducted from the circuit board to the metal plate having a low thermal resistance.
- the metal plate extends to the outer peripheral side from the circuit board, and the heat transferred to the metal plate diffuses in the surface direction. This prevents heat from being locally transferred from the electronic component to the rechargeable battery.
- the portable terminal of the present invention is characterized in that, in the above configuration, the mounting surface of the circuit board is arranged facing the bottom surface of the cabinet, and the bottom surface of the cabinet and the electronic component are opposed to each other with a gap. It is said. According to this configuration, air has a higher thermal resistance than the circuit board. Also, the amount of heat is likely to move in the direction of low thermal resistance. For this reason, the heat generated from the electronic component is transferred from the circuit board to the rechargeable battery side, and hardly transferred to the bottom surface of the opposite cabinet. Therefore, the heat generated in the electronic component is prevented from being locally transferred to the cabinet.
- heat generated from the electronic component is transferred from the circuit board to the rechargeable battery.
- the rechargeable battery has a large heat capacity, and the heat transferred is stored and diffused by the rechargeable battery. Thereby, it can prevent that a rechargeable battery interrupts
- the rechargeable battery can be used to dissipate electronic components, and the manufacturing cost of the portable terminal can be reduced.

- the display panel 11 is arranged on the surface of the portable terminal 1 and the back side is covered with a cabinet 15.
- the cabinet 15 is formed of a metal such as aluminum, and is formed in a box shape in which a peripheral wall 15b is erected from the periphery of the bottom surface 15a and an upper surface is opened.
- a circuit board 14, a metal plate 13, and a rechargeable battery 12 are accommodated in the cabinet 15.
- the circuit board 14 has the electronic component 14 a mounted on the mounting surface 14 b, and the mounting surface 14 b is disposed to face the bottom surface 15 a of the cabinet 15.
- the electronic component 14a includes heat generating components such as a CPU (Central Processing Unit), a wireless circuit component, and a charging circuit component.
- the metal plate 13 is formed of aluminum or the like, and is fitted to the inner surface of the peripheral wall 15b of the cabinet 15 to reinforce the cabinet 15. Further, the metal plate 13 is formed so as to extend to the outer peripheral side from the circuit board 14, and has a peripheral wall 13 a erected from the peripheral portion to store the rechargeable battery 12.
- the rechargeable battery 12 is composed of a lithium ion battery or the like, and supplies power to each part of the mobile terminal 1.
- the rechargeable battery 12 is disposed in contact with the upper surface of the metal plate 13.
- the display panel 11 is arranged on the opening surface of the cabinet 15 made of a liquid crystal panel, an organic EL panel or the like.
- a touch panel is formed on the surface of the display panel 11. Information is displayed on the display panel 11 and the portable terminal 1 is operated.
