Fins of semiconductor are formed on the substrate. Each of the fins is located separately from one another. A gate insulating film is formed on side surfaces of the fins. A gate electrode is formed on the gate insulating film. The gate electrode extends to cross over the fins. A gate contact portion is provided to supply an electric signal. In the fins, first drain regions and first source regions are formed respectively so as to sandwich portions of the fins located below the gate electrode. A width of first one of the fins is larger than that of second one of the fins which is more distant from the gate contact portion than the first one of the fins.
