Abstract: 본 발명의 적층형 칩 인덕터는 코일의 역할을 하는 전극 패턴이 형성되어 있고 상기 전극 패턴과 연결되는 비어홀을 가지고 있으며 차례로 쌓여 있는 다수의 제1 세라믹 시트가 형성되어 있으며, 이 다수의 제1 세라믹 시트의 위, 아래에 각각 외부와 전기적으로 연결하기 위한 전극 패턴을 가지는 제2 및 제3 세라믹 시트가 형성되어 있다. 그리고, 제2 및 제3 세라믹 시트의 위, 아래에 각각 위, 아래에 각각 제1 및 제2 전자파 차폐용 금속 패턴을 가지고 있는 제4 및 제5 세라믹 시트가 형성되어 있다.
이때, 제1 및 제2 전자파 차폐용 금속 패턴은 코일의 중심부에 생기는 전자파를 차폐하므로, 본 발명에 따르면 적층형 칩 인덕터 제조 시 코일의 방향을 나타내는 마킹을 할 필요가 없다.-

Abstract: PURPOSE: A stack type chip inductor is provided to diminish cost and the number of processes by diminishing the number of masks for forming a conductive pattern which is formed on a ceramic sheet of stack type chip inductor. CONSTITUTION: The stack type chip inductor is formed of a number of ceramic sheets(1,2,3,4,5) stacked by turns. Conductive patterns(11,12,13,14,15), playing as a coil and electrically connected each other, are formed on the ceramic sheets(1,2,3,4,5), respectively. From the ceramic sheets(1,2,3,4,5), a conductive pattern(11) formed on a first ceramic sheet(1) placed at bottom and a conductive pattern(12) formed on a second ceramic sheet(2) placed at top have a same shape and are arranged to make a rotation symmetry about center of the ceramic sheet. Especially, the first and second ceramic sheets(1,2) are arranged to make 180 degree rotation symmetry, and one or more third ceramic sheet(s) is/are stacked between the first and second ceramic sheets. The third ceramic sheet(3) has a conductive pattern(13) electrically connected to the conductive patterns(11,12) of the first and second ceramic sheets.
