ABSTRACT:
A non-reciprocal circuit device has a length, a width, and a thickness denoted respectively by L1,L2,and L3,and the overall dimensions of 2.5 mm<L1<7.0 mm, 2.5 mm<L2<7.0 mm, and 1.0 mm<L3<3.5 mm. When a projected area of the substrate of the device is orthogonally projected on a plane parallel to a base surface of the substrate is denoted by S1, the substrate holds a proportional relation to S1/(L1×L2)=0.1 to 0.78. When a thickness of the magnet of the device is denoted by L4,the magnet holds a proportional relation of L4/L3=0.2 to 0.5. When a projected area of the magnet orthogonally formed on a plane parallel to a surface of the magnet is denoted by S2,they have a proportional relation of S1/S2=0.15 to 0.83.
