PROBLEM TO BE SOLVED: To suppress the effects of nonspecific adsorption without preventing the formation of a high-throughput sensor unit. SOLUTION: The sensor unit 10 comprises both a channel member 12 in which a plurality of channels 20 are formed and a prism 14 in which a metal film 25 is formed in its upper surface. A body 12a of the channel member 12 is molded approximately in a rectangular parallelepiped shape. Each channel 20 is formed approximately in a U-shape by both an approximately linear groove part 20c formed in the bottom surface of the channel member 12 and liquid feed and discharge tubes 20d and 20e passing through to the upper surface of the channel member 12 from both ends of the groove part 20c and each forming outlet and inlet openings 20a and 20b. The channels 20 are formed in such a way that the groove parts 20c may be along the width direction of the main body 12a and arranged at prescribed intervals in the longitudinal direction of the main body 12a.
