A planar plasmon antenna is formed on a YZ plane including a Z-axis, the Z-axis being a propagation direction of excitation light for near-field light generation. The longitudinal direction of the planar plasmon antenna is oblique relative to the Y-axis, and the angle of a corner of the planar plasmon antenna in the YZ plane is an acute angle. The corner, which forms an acute angle, generates intense near-field light in response to excitation light irradiation.
