An object of the present invention is to provide a semiconductor device including an oscillator circuit including a circuit between inverters. In the circuit, a sum of the length (a1) of a wiring path between a terminal A and a terminal C1 and a length (b1) of a wiring path between a terminal D1 and a terminal B is substantially equal to a sum of the length (a2) of a wiring path between the terminal A and a terminal C2 and the length (b2) of a wiring path between a terminal D2 and the terminal B.
