Abstract: An object of the present invention is to provide a stitched fiber-reinforced substrate material capable of suppressing the formation of microcracks in a fiber reinforced composite material. The stitched fiber-reinforced substrate material of the present invention is a stitched fiber-reinforced substrate material formed by stitching reinforcement fiber sheets made of reinforcement fibers using stitching yarns, to which an organic compound having a polar group is adhered. The organic compound having a polar group is preferably a compound having a polyoxyalkylene structure, and also preferably a compound having an epoxy group. The organic compound having a polar group is preferably adhered in an amount of 0.1 to 10 wt % with respect to the mass of the stitching yarn.
