Abstract
A non-reciprocal circuit device has a length, a width, and a thickness denoted respectively by LLand Land the overall dimensions of 2.5 mm<L<7.0 mm, 2.5 mm<L<7.0 mm, and 1.0 mm<L<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 S, the substrate holds a proportional relation to S/(L×L)=0.1 to 0.78. When a thickness of the magnet of the device is denoted by Lthe magnet holds a proportional relation of L/L=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 Sthey have a proportional relation of S/S=0.15 to 0.83.
