Magnetic coupling-type isolator
Magnetoresistive effect elements R1 to R4 are a TMR element or CPP-GMR element. A multilayer film forming the magnetoresistive effect elements is formed to have a width dimension T1 and a length dimension L1 perpendicular to the width dimension T1. The length dimension L1 is longer than the width dimension T1. The width dimension of magnetic field generators of the coil is T2. The multilayer film 31 is positioned within the width dimension T3 of 60% in total of 30% each to the width dimension T2 of the magnetic field generators 3 and 4 of the coil in the direction towards both sides from the center of the width dimension T2 when seen in a plan view.
