Zusammenfassung:	PURPOSE:To prevent the build-up of a center part and to prevent the short- circuit of a solder by providing a partition at the open part of the solder mask for coating a solder onto a printed circuit board. CONSTITUTION:When a partition 6 is put into the opening part 2 for coating a solder of a solder mask 1, the surface tension becomes larger as well with the creamy solder 5 coating being also divided and the area being reduced and such a phenomenon as the solder 5 popping out to the external part even if the part of an IC, etc., is mounted thereon is eliminated. A printed circuit board 3 difficult to cause a solder short circuit is thus obtd. easily without the need at all for the change, etc., of the working method and working route with the simple structure of providing the partition 6 at the open part 2.
