Abstract
A microchannel chip with which channel deformation does not occur even when high-temperature and high-pressure sterilization treatment is performed and with which strong joining performance of substrates is maintained; and a method for manufacturing the same are provided. A microchannel chip comprising: a channel substrate having a microchannel formed on at least one surface thereof; a lid substrate; and a joining layer joining the channel substrate and the lid substrate, wherein the channel substrate, the lid substrate, and the joining layer are each formed of a cycloolefin polymer, a glass-transition temperature Tgof a cycloolefin polymer forming the channel substrate, a glass-transition temperature Tgof a cycloolefin polymer forming the lid substrate, and a glass-transition temperature Tgof a cycloolefin polymer forming the joining layer have relationships: Tg>Tg; and Tg>Tg, and the joining layer has a thickness within a specific range.
