A semiconductor integrated circuit device 1 includes a plurality of basic cells 5 each having therein a logic transistor 2 that performs logical operations, and a power switching transistor 3 that can interrupt leakage current when the logic transistor 2 is not operated. The semiconductor integrated circuit device 1 further includes a wiring 6 that connects virtual power nodes 4 as the connection points between the logic transistors 2 and the power switching transistors 3, between individual basic cells 5a and 5b included in a plurality of basic cells 5. Here, a basic cell includes a power switching transistors 3 that can interrupt leakage current when the logic transistors 2 are not operated, in addition to the logic transistors 2. Thereby, switching transistors 3 can be disposed in the optimal positions of the cells 5, and basic cells 5 having a small restriction in disposition and wide scope of application can be provided.
