摘要：
A magnetic detection device has stable characteristics having an area of a resist layer covering an insulating passivation layer, forming the magnetic detection element and a connection layer on a small stepped surface with high-precision, and preventing the resist layer from peeling, thereby providing a method of manufacturing the magnetic detection device. A resist layer 42 is overlapped through the insulating passivation layer 41 on an interconnection layer 35.
