Zusammenfassung: | The present invention relates to a deposition film for a capacitor, which is configured by depositing metal thereon, and overlapping two sheets as one unit to face each other. A metallicon contact part (10), communicating with a metallicon of a capacitor, is formed at a widthwise end (1a) of a dielectric (1) through metal deposition. A margin part (20), which is not deposited with metal, is formed at the other widthwise end (1b) of the dielectric (1). Metal is deposited between the metallicon contact part (10) and the margin part (20) to form an operating area (A). The operating area (A) comprises: a first operating area (30) which is located on a widthwise side of the dielectric (1) and is adjacent to the metallicon contact part (10); and a second operating area (40) which is located on the other widthwise side of the dielectric (1) and adjacent to the margin part (20). A deposition thickness (t2) of the second operating area (40) is thinner than a deposition thickness (t1) of the first operating area (30).
금속이 증착되고 2매 1조로 대향되게 겹쳐서 이루어지는 커패시터용 증착 필름에 있어서, 유전체(1)의 폭방향 일측단(1a)에 커패시터의 메탈리콘와 통전하는 메탈리콘 접촉부(10)가 금속 증착으로 형성되고, 상기 유전체(1)의 폭방향 타측단(1b)에 금속이 증착되지 않은 마진부(20)가 형성되고, 상기 메탈리콘 접촉부(10)와 마진부(20) 사이에 금속이 증착되어 작동영역(A)이 형성되되, 상기 작동 영역(A)은, 유전체(1)의 폭방향 일측에 위치하고 상기 메탈리콘 접촉부(10)에 인접하는 제1 작동영역(30)과, 유전체(1)의 폭방향 타측에 위치하고 상기 마진부(20)에 인접하는 제2 작동영역(40)으로 구성되고, 상기 제2 작동영역(40)의 증착 두께(t2)는 상기 제1 작동영역(30)의 증착 두께(t1)보다 얇은 것을 특징으로 하는 2단식 커패시터용 증착 필름 |
