摘要：
A near-field light generator includes a plasmon generator including a plasmon exciting portion on which a surface plasmon is excited, and a near-field transducer including a front end face that generates near-field light from the surface plasmon. The near-field transducer is formed of a first metal material. The plasmon generator includes a first portion formed of the first metal material and a second portion formed of a second metal material. The first portion is in contact with the near-field transducer. The second portion includes at least part of the plasmon exciting portion.
