The thermally-assisted magnetic recording head includes: a magnetic pole having an end exposed on an air-bearing surface; a waveguide; a plasmon generator formed essentially of a first metallic material, and having a first region and a second region, the first region extending backward from the air-bearing surface to a first position, and the second region being coupled with the first region at the first position and extending backward from the first position; and a metallic layer filling a part in the second region, and formed essentially of a second metallic material that has a higher melting temperature than a melting temperature of the first metallic material.
