Sample analysis cartridge and method for manufacturing the same

Abstract

To provide a specimen analysis cartridge and the like with increased liquid leakage durability.SOLUTION: A specimen analysis cartridge includes a first substrate having a microfluidic channel formed on at least one surface thereof, a second substrate arranged opposite the surface on which the microfluidic channel is formed on the first substrate, and a photocurable resin layer by which the first substrate and the second substrate are bonded together. The first and second substrates include at least one of a cyclo-olefin polymer and a cyclo-olefin copolymer.SELECTED DRAWING: Figure 1
