In a perpendicular magnetic recording head in which a magnetic pole part of a main magnetic pole layer exposed at a medium-opposing surface exhibits a trapezoidal form narrower on the leading edge side than on the trailing edge side, a pair of partial side shield layers made of a soft magnetic material are provided on both sides in the track width direction of the magnetic pole part of the main magnetic pole layer such as to be located more on the leading edge side of the magnetic pole part.
