PROBLEM TO BE SOLVED: To provide a sealant composition most suitable for a solar battery module sealant with weather resistance, vibration resistance and productivity, and others.SOLUTION: A sealant composition is used to seal a solar battery module 5. The sealant composition comprises: a polyol component (A component); and at least one (B component) of aliphatic isocyanate and alicyclic isocyanate, provided that 93-100 wt.% of the A component consists of polyether polyol as described in (X) below. (X) The polyether polyol is produced by ring-opening addition polymerization of alkylene oxide with a compound having at least one of a hydroxyl group and an amino group, and has a mean functional group number is 2-4. |
