Zusammenfassung:	The present invention relates to a method for producing a mother plate and a method for producing a metal filter. The method for producing a mother plate (20) is provided to produce the mother plate (20) used in manufacturing a metal filter (10) using electroforming. The method comprises the steps of (a) providing a conductive substrate (21), and (b) irradiating a laser beam (L) on one surface of the conductive substrate (21) to form an insulating pattern layer (25). In the step (b), the insulating pattern layer (25) is formed in a region corresponding to a filter hole (H) of the metal filter (10) to be produced. 본 발명은 모판의 제조 방법 및 금속 필터의 제조 방법에 관한 것으로서, 모판(20)의 제조 방법은, 전주 도금(Electroforming)으로 금속 필터(10) 제조시 사용되는 모판(Mother Plate; 20)의 제조 방법으로서, (a) 전도성 기재(21)를 제공하는 단계, 및 (b) 전도성 기재(21)의 일면 상에 레이저(L)를 조사하여 절연 패턴층(25)을 형성하는 단계를 포함하고, (b) 단계에서, 제조될 금속 필터(10)의 필터공(H)에 대응하는 영역에 절연 패턴층(25)을 형성하는 것을 특징으로 한다.
