Plasmon generator including a heat sink layer interposed between two portions formed of different metal materials
A plasmon generator includes: a first portion formed of a first metal material and including a front end face configured to generate near-field light; a second portion formed of a second metal material and located at a distance from the front end face; and a heat sink layer formed of a third metal material, located at a distance from the front end face and interposed between the first portion and the second portion. The second metal material is lower in Vickers hardness and higher in thermal conductivity than the first metal material. The third metal material has a thermal conductivity higher than that of each of the first and second metal materials, and has a Vickers hardness lower than that of the first metal material and higher than that of the second metal material.
