Abstract

PURPOSE:To simply insulate a metal plate exposed on the inner peripheral wall of a through hole and to simply perform a through hole plating step by forming an insulating substance by an electrodepositing painting using a metal plate as an electrode. CONSTITUTION:After the step of forming a through hole is finished, the exposed face 5a of the metal plate 5 of the inner peripheral wall 7a of a through hole 7 is covered with an insulating substance 8. This step is performed by electrodepositing painting. In this case, the plate 5 is used as an electrode (in case of anion type electrodepositing painting, it becomes an anode, while in case of cation type electrodepositing painting, it becomes a cathode). When one end extends externally from insulating layers 6, 6 laminated elevationally, its operability is improved. After the step of electrodepositing is finished, a through hole plating is performed to form a through-hole plating layer 6 on the inner peripheral wall 4a of the hole 4 and the peripheral edge of the opening of the hole 4.
