Provided are a laminate that can be used as a microchannel chip that maintains joint strength while also displaying good external appearance and having reduced risk of liquid leakage from a channel and a method for manufacturing the same. The laminate includes a channel-equipped substrate having a cycloolefin polymer as a material and a cover material having a cycloolefin polymer as a material that are joined via a joining agent having a mixture of two or more cycloolefin polymers as a material. A glass-transition temperature of the mixture of cycloolefin polymers that is a material of the joining agent is not less than 20°C lower than both a glass-transition temperature of the cycloolefin polymer that is a material of the channel-equipped substrate and a glass-transition temperature of the cycloolefin polymer that is a material of the cover material and is not lower than 68°C and not higher than 138°C.
