A heat-assisted magnetic recording head includes a magnetic pole, a waveguide, a near-field light generating element, and a substrate on which they are stacked. The near-field light generating element and the waveguide are disposed farther from the top surface of the substrate than is the magnetic pole. The near-field light generating element has an outer surface including: a first end face located in the medium facing surface; a second end face farther from the medium facing surface; and a coupling portion coupling the first and second end faces to each other. The first end face includes a near-field light generating part. The waveguide has an outer surface including an opposed portion opposed to a part of the coupling portion. The head further includes a mirror that reflects light emitted from a light source disposed above the waveguide, so as to let the light travel through the waveguide toward the medium facing surface.
