Provided is a semiconductor integrated circuit device capable of realizing an analog circuit required to have a high-precision relative ratio between adjacent transistors, which is reduced in size and cost. A single MOS transistor is provided within each of well regions. A plurality of the MOS transistors is combined to serve as an analog circuit block. Since distances between the well regions and channel regions may be made equal to one another, a high-precision semiconductor integrated circuit device can be obtained.
