The purpose of the present invention is to provide: a microchannel chip in which channels do not deform even when subjected to a high-temperature and high-pressure sterilization treatment, and in which strong bonding properties between substrates can be maintained; and a method for manufacturing the microchannel chip. The microchannel chip according to the present invention comprises a channel substrate in which microchannels are formed on at least one surface, a lid substrate, and a bonding layer that bonds the channel substrate and the lid substrate, and the channel substrate, the lid substrate, and the bonding layer are configured from a cyclic olefin polymer. The relationship among the glass transition temperature (Tgs1) of the cyclic olefin polymer constituting the channel substrate, the glass transition temperature (Tgs2) of the cyclic olefin polymer constituting the lid substrate, and the glass transition temperature (Tg2) of the cyclic olefin polymer constituting the bonding layer is Tgs1 > Tg2 and Tg
