Abstract: A semiconductor device comprising a low-heat-resistance heat discharging route suitable for small semiconductor devices, such as an IC card, is disclosed. Heat arising from electronic parts is efficiently dispersed to the outside, thereby accomplishing a decrease in size and a heightening of function. In a specific embodiment, a CPU is mounted on a substrate in a position of thermal via holes.
