PURPOSE:To obtain an air escape passage in a through hole at the time of coating and to effectively conduct a wiring pattern with a conductor by coating the through hole covered with the conductor at the other side opened at a printed board with conductive paste in a different shape coating pattern shape. CONSTITUTION:A cross shape through hole 9a in a plane figure is opened at a predetermined position of a base film 9 of a flexible printed board (FPC) 8. Each hole 9a is coated with conductive paste 12 such as As paste, etc., by using a dispenser. In this case, it is superposed with a land 10a in the shape of the paste 12 and a substantially circular coating pattern shape in which the protruding end of the hole 9a is exposed is formed. Accordingly, since the paste 12 is effectively brought into contact with the land 10a at the time of coating and the air in the hole 9a can be released, a roundabout pattern 10 can be effectively conducted with an opposed electrode 7. |
