To provide an organic and inorganic composite filler which gives excellent surface smoothness similar to that of a natural tooth, low polymerization shrinkage, high X-ray imaging property and high mechanical strength to a dental restoration material composite, an organic and inorganic composite filler used for a dental restoration material is produced by curing and pulverizing a (meth)acrylate compound including 50 to 80% by weight of a glass powder having a maximum particle diameter of 5 .mu.m or less, an average particle diameter from 0.05 to 2 .mu.m, and X-ray imaging property, and 10 to 40% by weight of a metal compound having an average particle diameter from 0.005 to 0.3 .mu.m and X-ray imaging property at the maximum of 90% by weight in total, where the organic and inorganic composite filler has preferably an average particle diameter from 10 to 30 .mu.m.
