摘要：
A magnetoresistance effect type head comprises a magnetoresistance effect film having a pair of leads connected thereto and possessing a magnetic field responding part and a pair of upper and lower shield layers having a magnetoresistance effect film nipped therebetween through the medium of a magnetic gap-forming insulating film. This magnetoresistance effect type head satisfies the relations, W.sub.s
