To provide a method of manufacturing a resin laminate, which is excellent in the appearance of the adhesive after cured and has excellent cured state, by means of an adhesive polymerizable and curable at a normal temperature.

A method of manufacturing a resin laminate includes: injecting an adhesive containing a (meth)acrylic radically polymerizable monomer (A), an azo-based polymerization initiator (B) having 20-40°C ten-hour half-life temperature and an azo-based polymerization initiator (C) having 45-60°C ten-hour half-life temperature between a resin molded article and another resin molded article; performing polymerization and curing under an atmosphere of 20-28°C; performing annealing at ≥95°C, and performing cooling.
