MANUFACTURING METHOD OF WIRING CIRCUIT BOARD

摘要

PROBLEM TO BE SOLVED: To provide a wiring circuit board formed by adhering a wiring pattern to have a more fine wiring pattern shape. SOLUTION: The manufacturing method of wiring circuit board comprises the steps of forming an insulating layer on a first wiring formed on a core circuit board, transferring a second wiring to the relevant insulating layer by pressing the relevant second wiring formed on a supporting circuit board to the insulating layer, removing the relevant supporting circuit board, and forming a via plug for connecting the first wiring and the second wiring.
