The present invention provides an aqueous dispersion of a urethane resin (X) that uses a nonionic group-containing compound (a1) as a raw material, wherein the nonionic group-containing compound (a1) has a use rate of 5% by mass or less based on the total mass of raw materials constituting the urethane resin (X), the aqueous dispersion has an anionic emulsifier (Y1) content of 7 parts by mass or less with respect to 100 parts by mass of the urethane resin (X) and does not include an organic solvent during a production step. Further, the invention provides a leather sheet, wherein a coagulated product of the urethane resin aqueous dispersion is present in a fiber substrate. It is preferable that in the leather sheet, a coagulated product of the urethane resin aqueous dispersion is present in the fiber substrate.
