1. Reinforcing fibers, comprising:
surface-modified fibers containing fibers and a surface-modifying layer that covers at least a part of a surface of the fibers and has a surface with a solid surface zeta potential of −20.0 to 30.0 mV, and
an adhesive layer containing conjugated diene-based rubber that covers at least a part of a surface of the surface-modified fibers and has a number average molecular weight (Mn) of more than 2,000 and 120,000 or less.
