A semiconductor integrated circuit includes: a logic circuit section including transistors formed on an SOI substrate; and a partially-depletion-type transistor, which is formed on the SOI substrate as a switching transistor for controlling ON/OFF states of the logic circuit section and which has a body contact portion. The partially-depletion-type transistor has a threshold voltage, which is substantially equal to that of the transistors in the logic circuit section when no potential is applied to the body contact portion and which is higher than that of the transistors in the logic circuit section when a potential is applied to the body contact portion.
