<p>PROBLEM TO BE SOLVED: To provide a printed circuit board that allows preventing a component to be protected from static electricity by using potential difference formed between two spark gaps having different materials provided between a ground pattern and the component to be protected.SOLUTION: A printed circuit board according to the present invention includes a ground pattern, a component to be protected, and spark gaps interposed between the ground pattern and the component to be protected. The spark gaps are composed of a first metal pattern coupled to the ground pattern and a second metal pattern formed to spaced apart from the first metal pattern with a predetermined distance, so that static electricity due to potential difference can be induced to the ground, thereby protecting an electrostatic-sensitive component.</p> |
