A liquid organosilicon compound comprising a structural unit represented by the following formula (1-a) and a structural unit represented by the following formula (1-b): In the above formula (1-a), R1 each independently is a group selected from an alkyl having 1 to 4 carbon atoms, cyclopentyl and cyclohexyl and in the above formula (1-b), R2 and R3 each independently are a group selected from an alkyl having 1 to 4 carbon atoms, cyclopentyl and cyclohexyl, and n is an integer of 2 to 50. When a mole fraction of the structural unit represented by the formula (1-a) in the liquid organosilicon compound isαand a mole fraction of the structural unit represented by the formula (1-b) in the liquid organosilicon compound isβ, the ratio ofαand n×β(α:n×β) meets 1:3 to 1:100.
