Abstract: A method for producing a prepreg, includes the steps of (1) an opening step of opening glass fiber bundles to form plural glass fiber filaments, and (2) a step of aligning the plural glass fiber filaments formed in the previous opening step, on a thermosetting resin composition-coated surface of a carrier material so as to make the filaments run nearly parallel to each other in one direction thereon to form a prepreg. A method for producing a laminate, includes a step of preparing two or more prepregs formed in the previous step (2), laminating them in such a manner that, in at least one pair of prepregs, the running direction of the plural glass fiber filaments in one prepreg differs from the running direction of the plural glass fiber filaments in the other prepreg, and heating and pressing them.
