PROBLEM TO BE SOLVED: To provide a semiconductor device with a electrostatic discharge protection circuit. SOLUTION: There is provided a semiconductor device, having an input/output signal line for connecting an input/output pad and an internal circuit. A first electrostatic discharge (ESD) protection circuit, is diverged from the input/output pad and connected to a power source line. A second ESD protective element is diverged from the input/output pad and connected to a ground line. A resistor is formed on the input/output signal line, and a capacitor branched from the power source line is formed between the power source line and the resistor. COPYRIGHT: (C)2006,JPO&NCIPI
