Provided is an organosilicon compound characterized by containing at least one group represented by structural formula (1) in one molecule and having a main chain comprising a silicon-containing organic group. This organosilicon compound exhibits satisfactorily fast curability, and excellent yellowing resistance, heat resistance, storage stability, and safety.

(In the formula, each R 1 independently represents an unsubstituted or substituted C1-10 alkyl group, or an unsubstituted or substituted C6-10 aryl group, each R 2 independently represents an unsubstituted or substituted C1-10 alkyl group, or an unsubstituted or substituted C6-10 aryl group, and each R 3 independently represents a hydrogen atom or an unsubstituted or substituted C1-10 alkyl group. m is a number from 1-3, and n is an integer of 2 or greater. A dashed line represents a bond.)
