Abstract
A sheet-like reinforcing fiber base material reduces waste in production of a fiber-reinforced resin molded product and has a small position shift of a reinforcing fiber base material for reinforcement, as well as a preform and a fiber-reinforced resin molded product. The sheet-like reinforcing fiber base material is configured to maintain a sheet-like form by arraying and arranging reinforcing fiber bundles such that longitudinal directions thereof are one identical direction and restraining positions of adjacent reinforcing fiber bundles with respect to each other. In the sheet-like reinforcing fiber base material, the placement amount of reinforcing fibers is partly increased, such that the placement weight of reinforcing fibers per unit area is non-uniform.
