PROBLEM TO BE SOLVED: To dispose a protector for electrostatic destruction preventing function of an integrated circuit, without pressing chip area. SOLUTION: An internal circuit 10, such as logic circuit, memory circuit and analog circuit, is disposed in an internal area 2. Two of power supply wirings 11A, 12A for an input/output circuit of the internal circuit 10 for supplying power to the input/output circuit, power supply terminals 19A, 20A connected to the power supply wiring, and two power supply terminals 13A, 14A for the internal circuit 10 are disposed in a chip peripheral region 3. Between two of power supply wiring 11A, 12A for the input/output circuit, power supply wiring 11A is separated at a position near the internal circuit 10 and separate wiring 15 is formed. The separate wiring 15 is connected with the one power supply terminal 14A between the two power supply terminals 13A, 14A for the internal circuit 10. A protector 16, for the two power supply terminals 13A, 14A for the internal circuit 10, is disposed in the chip peripheral area 3, and the protector 16 is connected with the separate wiring 15 and the other power supply terminal 13A between the two power supply terminals 13A, 14A for the internal circuit 10.
