PRISM PART OF ANALYSIS CHIP, ANALYSIS CHIP INCLUDING THE PRISM PART, AND METHOD FOR PRODUCING A PRISM PART OF ANALYSIS CHIP

摘要

The present Invention is a prism part (20) which is included In an analysis chip (10) of an analysis device for analyzing a specimen using surface plasmon resonance and forms, in collaboration with a flow path member (12), a flow path (13) through which a sample solution including the specimen flows, and is provided with a prism body (21) which excitation light for generating surface plasmon enters, and a gold film (25) which is provided on a specific surface (23) of the prism body (21). The prism body (21) has a mixed layer (28) having a predetermined thickness from the specific surface (23) to the inner side, and the mixed layer (28) Is characterized by being formed by the entry of gold constituting the gold film (25) in an ionized state from the specific surface (23) when the gold film (25) is formed on the specific surface (23).
