Abstract
An SPR sensor includes an SPR sensor cell. The SPR sensor cell includes an optical waveguide to be brought into contact with a sample. The optical waveguide includes an under clad layer, a core layer provided in the under clad layer such that at least a portion thereof is exposed from the under clad layer, a metal layer covering the core layer exposed from the under clad layer, and a cover layer to be brought into contact with a sample, the cover layer covering the metal layer. The water wettability of the cover layer is higher than water wettability of the metal layer.
