Abstract
A magnetic coupling type isolator includes: a magnetic field generator for generating an external magnetic field by an input signal; a magnetoresistive element for detecting the external magnetic field and converting the detected magnetic field into an electric signal, the magnetoresistive element being electrically insulated from the magnetic field generator and positioned in a location capable of being magnetically coupled so as to be overlapped with the magnetic field generator as seen in a top plan view; and first and second shield films overlapped with the magnetic field generator and the magnetoresistive element as seen in a top plan view, wherein a distance between the magnetoresistive element and the second shield film is set to 8 to 100 μm.
