In a magnetoresistance element including a lower electrode layer which is formed directly on a lower shield layer or on another layer which is formed on the lower shield layer or so as to serve also as the lower shield layer; a magnetoresistance effect layer which is formed on part of the upper surface of the lower electrode layer; and an upper electrode layer which is formed above the lower electrode layer so that part of its lower surface will at least be in contact with the upper surface of the magnetoresistance effect layer, the upper electrode layer is formed so that the upper electrode layer seen in a plan view will avoid the edge of the lower electrode layer except at the ABS (Air Bearing Surface) of the magnetoresistance element. In such composition of the magnetoresistance element, no part of the upper electrode layer exists above the edge of the lower electrode layer, therefore, electrical shorts between the upper electrode layer and the lower electrode layer can be avoided even if the roughness of the edge of the lower electrode layer (which is exposed to a release agent containing a dissolved photoresist in a photoresist layer removal step) increased, thereby a magnetoresistance element of high sensitivity and high performance can be obtained and manufacturing yield of the magnetoresistance elements can be improved.
