By voltage limiting means, which provided in an IC as one of the components of an electronic apparatus, and a resistor, which is provided between a voltage input terminal of the IC and an external terminal of the electronic apparatus, an unexpected abnormal voltage generated in a DC power source such as an AC adaptor can be limited, and an overvoltage of not less than a predetermined value can be also prevented from being applied to the IC.
