An ambient-temperature curable organopolysiloxane composition is provided to ensure excellent storage stability before curing, and good adhesion to metals and various paints after curing, and exhibit rubber elasticity with the low modulus of elasticity. An ambient-temperature curable organopolysiloxane composition includes (a) 100 parts by mass of diorganopolysiloxanes represented by the following formula 1 or 2, (b) 0.1-10 parts by mass of triorganosilanols represented by the formula 3 of R^2_3SiOH(wherein, R^2s are the same and different substituted or unsubstituted monovalent hydrocarbon groups having 1-20 carbon atoms), (c) 1-20 parts by mass of organosilanes having at least 3 hydrolyzable groups in a molecule and/or partially-hydrolyzed products thereof, and (d) 10-300 parts by mass of calcium carbonate. |
