Measuring chip for a surface plasmon resonance measurement apparatus

摘要

A measuring chip (10) comprising a dielectric block (11) and a thin film layer (12) formed on one surface (11a) of the dielectric block (11). The thin film layer (12) is used for placing a sample (15) thereon. The dielectric block (11) is formed as a single block, which includes an entrance surface (11b) at which a light beam (30) enters the dielectric block (11), an exit surface (11c) from which the light beam emerges, and the one surface (11a) on which the thin film layer (12) is formed. In addition, the dielectric block (11) is integrated with the thin film layer (12) and formed from a resin whose photoelastic coefficient is less than 50 x 10<-12> Pa<-1>.
