A semiconductor device includes a semiconductor substrate and a current mirror circuit that has an input transistor group of input transistors and an output transistor group of output transistors. The input transistor group and the output transistor group are arranged on the semiconductor substrate in such a manner that at least one of the input transistors and at least one of the output transistors are grouped together to form a transistor set. Each transistor set is arranged in a repeating pattern. In each transistor set, the transistors have the same temperature and show the same temperature dependence, even when a temperature gradient occurs inside the semiconductor device. Thus, a mirror ratio of the current mirror circuit can be accurately obtained.
