To make only twice printing enough for applying printing over four surfaces and realize the adhesion to all the electronic parts with no electrically conductive material left in screen holes.

A mask having screen holes, the diameter of each of which is larger than the diameter of each electronic part as a body to be printed, is employed so as to firstly print the surface on one side of the electronic part. At this printing, the upper part side of the mask is pressurized by the air simultaneously with the finish of printing by a squeegee. Simultaneously with the pressurization, the electronic parts are lowered so as to separate from the under surface of the mask and then dried under heat. After drying, the electronic parts are turned upside down so as to print the surface on the other side of each of the electronic parts through the same process as the above one.
