Abstract
A magnetic sensor including a magnetoresistive effect element has the following structure. Element units each having an element width Wand an element length Lperpendicular to the element width Wand producing a magnetoresistive effect in which electrical resistance changes in response to an external magnetic field are arranged in an element-length direction with a space therebetween. An intermediate permanent magnet layer is disposed in the space, and the element units are connected to each other with the intermediate permanent magnet layer therebetween to form a connected-element body. A plurality of the connected-element bodies are arranged so as to be adjacent to one another in an element-width direction with a space therebetween, the ends of the connected-element bodies are connected to each other with an outer permanent magnet layer therebetween to form a magnetoresistive effect element having a meandering shape.
