The present invention relates to a method for manufacturing a perpendicular recording magnetic head. The method for manufacturing a perpendicular recording magnetic head according to the present invention includes first to third steps. At the first step, a main magnetic pole layer is formed on a foundation layer. At the second step, a main magnetic pole forming mask whose recording-medium-facing surface is of an inverted trapezoidal shape is formed on the main magnetic pole layer. At the third step, a main magnetic pole whose recording-medium-facing surface is of an inverted trapezoidal shape is formed by performing ion milling on a laminated structure including the foundation layer and the main magnetic pole layer from a direction which makes a given angle with a lamination direction according to a bevel angle of the inverted trapezoidal shape.
