Zusammenfassung:	To provide a composition for sealing a coated wire, which achieves both water resistance and thermal shock resistance in high-temperature and high-humidity conditions.SOLUTION: The composition for sealing a coated wire contains (a) an alkyl-2-cyanoacrylate, (b) a polyfunctional (meth)acrylate whose cured product has a Shore D hardness of 60 or less, and (c) a 2-cyanoacrylate having an ether bond in an ester residue. The content of (b) is 35-55 mass% based on the total amount of the composition. The content of (c) is less than 10 mass% based on the total amount of the composition.SELECTED DRAWING: None 【課題】高温多湿条件での耐水性と耐冷熱衝撃性を両立する被覆電線シール用組成物を提供すること。【解決手段】（ａ）アルキル−２−シアノアクリレート、（ｂ）硬化物のショアＤ硬度が６０以下の多官能（メタ）アクリレート及び（ｃ）エステル残基にエーテル結合を有する２−シアノアクリレートを含有してなり、（ｂ）の含有量は、組成物の全量を基準にして、３５〜５５質量％であり、（ｃ）の含有量は、組成物の全量を基準にして、１０質量％未満であることを特徴とする被覆電線シール用組成物。【選択図】なし
