摘要： An information device is an information device that records information on or reproduces information from an information recording medium (3). The information device includes a light source (14) and a near-field light generating element (9) including a resonating section (22) configured such that plasmon resonance occurs between the resonating section (22) and a recording region (4). The resonating section (22) causes the plasmon resonance when emission light from the light source is irradiated on the near-field light generating element (9). A resonance enhancing film enhances the plasmon resonance between the resonating section (22) and the recording region (4). The resonating section (22) generates near-field light and irradiates the near-field light on the recording region (4) from a recording layer side.
