Abstract:
An irreversible circuit device comprising:a yoke main body having sidewall portions defined by an upper yoke and a lower yoke, and accommodating therein a magnetic substrate, a plurality of line conductors arranged on a main plane of said magnetic substrate while being individually insulated from one another, a plurality of capacitor substrates arranged around said magnetic substrate and a magnetic member for applying a DC bias magnetic field in substantially a vertical direction to the main plane of said magnetic substrate; wherein said plurality of line conductors is put one upon another on a main surface side of said magnetic substrate and are connected to one another on an opposing surface side of said magnetic substrate, each end of said line conductors put one upon another on the main surface side of said magnetic substrate is connected to said capacitor substrate, and a gap portion for magnetically insulating said upper yoke and said lower yoke is formed on a sidewall portion of said yoke main body.
