A perpendicular magnetic recording head capable of effectively inducing a recording magnetic field to a main magnetic pole front end portion and suppressing an occurrence of side fringing is provided. An auxiliary magnetic pole layer, which is a first magnetic portion, and a main magnetic pole layer, which is a second magnetic portion, disposed leaving a space to the above-described auxiliary magnetic pole layer are included, and a coil layer which applies a recording magnetic field to the above-described space between the auxiliary magnetic pole layer and the main magnetic pole layer is included. A yoke layer is disposed in contact with the above-described main magnetic pole layer, and the width dimension of the yoke layer is increased stepwise or continuously toward the rear in the height direction and the width dimension is increased stepwise or continuously from an upper surface toward a lower surface.
