An EVOH resin composition excellent in inorganic compound dispersibility and a method of producing an EVOH resin composition excellent in productivity and inorganic compound dispersibility are provided. The EVOH resin composition contains an EVOH resin (A) and an inorganic compound (B), and has a crystallinity of not lower than 36%. The EVOH resin composition is produced by: feeding an EVOH resin (A), an inorganic compound (B) and water (C) into a kneading apparatus including a screw-type side feeder (3); melt-kneading the resulting EVOH resin mixture while driving the screw-type side feeder (3); and expelling water vapor from the screw-type side feeder (3) to reduce the water content of the EVOH resin mixture to lower than 5 weight % while suppressing leakage of the EVOH resin kneaded body from the screw-type side feeder (3).
