A mobile terminal device according to the present invention is equipped with a housing (10) having laminated carbon fibre layers (21-24). Among the carbon fibre layers (21-24), the carbon fibers of the outermost carbon fibre layer (21) of the housing (10) are oriented in the length direction (d1) of the housing. This carbon composite material exhibits properties such as high heat conductivity along the direction of the carbon fibres, and high strength. As a result of this configuration, the diffusion of heat can be prioritized in the length direction (d1) of the housing (10), and strength of the housing (10) in the length direction can be improved. |
