PROBLEM TO BE SOLVED: To provide a small-sized nonreversible circuit element with high mass- productivity and an excellent electric characteristic whose capacitor part of which is configured compact. SOLUTION: This invention provides the nonreversible circuit element provided with 3 strip lines that are insulated from each other and overlapped so as to be in crossing with each other at a prescribed angle, a ferrite board closely placed to the strip lines, a magnet that magnetizes the ferrite board, 3 capacitors respectively connected to the strip lines, and a case that contains the components above and acts like part of a magnetic circuit, and the 3 capacitors are formed in one capacitive board containing a magnetic substance and the capacitive board is placed between the ferrite board and the case close to the ferrite board.
