Abstract: A phase difference film composed of a resin containing a copolymer including polymerization units A and B, the phase difference film including a cylindrical phase separation structure that generates a structural birefringence, the phase separation structure including a phase (A) having the polymerization unit A as a main component and a phase (B) having the polymerization unit B as a main component, and the phase difference film satisfying the following condition (1) or (2). Condition (1): D(A)>D(B) and f(B)>0.5, and a direction giving a maximum refractive index among in-plane directions and an orientation direction of a cylinder in the phase separation structure are parallel to each other. Condition (2): D(A)>D(B) and f(A)>0.5, and a direction giving a maximum refractive index among in-plane directions and an orientation direction of a cylinder in the phase separation structure are orthogonal to each other.

Abstract: 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.

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 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, and the joining layer has a thickness within a specific range.
