A fabricating method for a multi-layer printed circuit board comprises the steps of: attaching a releasing film at upper and lower surfaces of a center layer and attaching a first metal film to the releasing film, thereby forming a base member; forming a first connection portion on the first metal film by an electroplating process; forming a connection portion that a second connection portion is integrally formed with the first connection portion on the first connection portion; forming a second metal film on the second connection portion so as to be electrically connected to the connection portion; and etching a specific part of the second metal film and thereby forming copper patterns.
