A novel organosilicon compound having a β-ketoester structure and a pressure-sensitive adhesive composition for a liquid crystal element that includes the organosilicon compound are provided. The organosilicon compound is obtained by reacting, in the presence of a transition metal catalyst, a compound represented by a formula (1): [wherein, R1 represents H or Me, R2 to R4 represent divalent hydrocarbon groups, A represents a group of a formula (i): (wherein, R6 represents an alkyl group or a phenyl group), R5 represents a group of a formula (ii): (wherein, B represents OH or a group represented by the formula (i)), and p, q and r represent integers of 0 to 6] with an alkoxysilane represented by a formula (2): (R7O)m(R8)(3-m)Si—H   (2) [wherein, R7 and R8 represent monovalent hydrocarbon groups of 1 to 4 carbon atoms, and m represents 1, 2 or 3].
