(57) [Problem] To stably produce a condensate of a medium molecular weight of an organic trialkoxysilane. SOLUTION: When an organic trialkoxysilane is hydrolyzed and condensed into a condensate, a cation exchange resin containing no water is present, and a weight average molecular weight of 1,000 to 50, 000. A method for producing an organic trialkoxysilane condensate, which is a condensate of 2,000. |
