Abstract
A first side shield has a first sidewall and a second sidewall, and a second side shield has a third sidewall and a fourth sidewall. The first to fourth sidewalls have first to fourth edges, respectively, that are farthest from a top surface of a substrate. The distance between a rear end of the first edge and a rear end of the third edge in a track width direction is greater than the distance between a front end of the first edge and a front end of the third edge in the track width direction. The distance between the second edge and the fourth edge in the track width direction increases with increasing distance from the medium facing surface.
