The second side shield has third and fourth sidewalls. Each of the second and fourth sidewalls has a top edge farthest from a top surface of a substrate. The top edge of each of the second and fourth sidewalls is parallel to a medium facing surface. A portion of a top surface of the bottom shield, the first sidewall, and the third sidewall define a receiving section to receive a portion of the main pole. The receiving section has a bottom including a first inclined portion, a second inclined portion, and a third inclined portion.
