The purpose of the present invention is to provide: 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. A microchannel chip according to the present invention includes: 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. The channel substrate, the lid substrate, and the joining layer are each formed of a cycloolefin polymer. A glass-transition temperature Tgs1 of a cycloolefin polymer forming the channel substrate, a glass-transition temperature Tgs2 of a cycloolefin polymer forming the lid substrate, and a glass-transition temperature Tg2 of a cycloolefin polymer forming the joining layer have relationships Tgs1 > Tg2 and Tgs2 > Tg2. The joining layer has a thickness that is within a specific range.
