Provided is an ESD protection circuit for CDM capable of preventing a high current from flowing and preventing breakage when a battery is connected with reverse polarity. The ESD protection circuit employs a circuit configuration in which transistor elements are interposed in series to OFF transistors (11 and 13) included in the ESD protection circuit for CDM so that parasitic diodes of the transistor elements are connected to parasitic diodes of the OFF transistors in a reverse direction.
