断を発生させないプリント基板を提供することにある。Problems to be Solved by the Invention However, with the increase in the number of surface-mounted components, the number of heat treatment processes such as reflow and heat curing of adhesives has increased, and especially in the case of printed circuit boards using paper phenol base materials, the base material becomes brittle due to the heat treatment process. However, when the pattern is divided along the perforations, there are problems in that gaps occur and the pattern in the vicinity is cut. SUMMARY OF THE INVENTION An object of the present invention is to provide a printed circuit board that does not cause fringes or pattern cutting by changing the shapes of holes and slits that constitute perforations, in order to solve the above-mentioned conventional problems.

A hole 11.21 and a slit 12.
By providing the perforations formed by 22, the pattern can be divided without causing any separation or cutting of the pattern. Note that the corners may be provided with a small radius in order to prevent cracks from occurring at the corners when the printed circuit board is punched out using a mold.
