PROBLEM TO BE SOLVED: To provide a reinforced fiber sheet material high in configuration stability with a structure prevented from stitch misalignment and also excellent in resin impregnation tendency. SOLUTION: The reinforced fiber sheet has the following structure: Chain knit yarns 2 forming respective chain designs W are disposed between reinforcing fiber bundles 1 and 1, respective reinforcing insert yarns 3 knitted in these chain designs W are disposed for each given course, joining in a tensed condition the chain designs W each other at least a plurality of wales apart from each other including points where at least the plurality of reinforcing fiber bundles 1 are knittedly joined to the chain designs W set apart from each other and arranged laterally to each other, and nipping both sides of the reinforcing fiber bundles 1. Further, at least part of the reinforcing insert yarns 3 include thermofusing yarns 31 containing a low-melting thermoplastic resin on the yarn surface, and such a technical means is adopted that the low-melting thermoplastic resin is melted on undergoing heat treatment and fused on the reinforcing fiber bundles 1, thereby firmly sticking both of these members each other.
