<p>A near-field light emitting device (100a) includes a deflecting unit (132a) that deflects electromagnetic waves propagated through a core toward a base (110a). A propagating unit arranged on the base emits near-field light from an outlet. By providing a magnetic head on a side opposite to the base (110a), a distance between the magnetic head and an intensity center of the near-field light can be minimized. The deflecting unit is formed comparatively thick, therefore, the electromagnetic wave is caused to enter the propagating unit at such an angle that causes a surface-propagating wave to be generated highly efficiently.</p> |
