PROBLEM TO BE SOLVED: To provide a laminate, a halogen-free composite laminate in particular, which is obtained by using a resin composition constituted mainly of a radical polymerizable resin, which excels in toughness, heat resistance and water resistance and has such a low thermal expansion coefficient that the average linear expansion coefficient (10<SP>-6</SP>/°C) in a temperature range of 40-100°C is 20 or below, which can be worked and used at a high temperature and compares favorably in performance in place of an expensive material such as an epoxy resin used so far, and which excels also in fire retardance and can be manufactured inexpensively. SOLUTION: A halogen-free low-thermal-expansion composite laminate having all of the above features together is obtained by stacking and curing fiber-reinforced layers which are impregnated with resin compositions prepared respectively by compounding specified quantities of thermoplastic resins with a halogen-free radical polymerizable resin, a radical polymerizable monomer, a fire retardant and an inorganic filler.
