すことがない構造を提供することを目的とする。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a printed circuit board in which a conductor pattern is printed on an insulating substrate to form a circuit network, and a part of the insulating portion of the insulating substrate is fixed to an electrical device with a metal fastener. Even if an abnormal signal such as surge or noise is input to the printed circuit board through a metal fastener, the structure must be such that the abnormal signal will not have a negative effect on other electronic components or circuits on the printed circuit board. The purpose is to provide.

成している。The present invention will be explained below based on drawings showing embodiments thereof. In Figs. 1 to 3, -1 is an insulating board constituting a printed circuit board. On this insulating board 1, a conductor pattern 2 made of copper foil is entirely printed to form a circuit network, and on top of it is soldered. An anti-adhesion coating layer 3 is formed over the entire surface.

With this shape, even if an abnormal signal such as a surge or noise is input to the insulating board 1 constituting the printed circuit board via the metal fasteners 6 such as screws, it will not reach the metal fasteners 6 at close range. Since a ground circuit is formed, the abnormal signal is grounded preferentially over this ground circuit, and as a result, other electronic components and circuits on the insulating substrate 1 are not adversely affected.

の形成により。As described above, according to the present invention, a conductor pattern, one end of which is connected to a ground circuit, is extended and printed in a shape that surrounds the contact portion of the insulating substrate with the metal fastener at a certain distance. Therefore, even if an abnormal signal such as a surge or noise is input to the insulating board through the metal fastener, the ground circuit will be formed.
