Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a curable composition capable of maintaining excellent rubber elasticity over a long period of time after curing while having flame retardancy.SOLUTION: The curable composition of the present invention contains: a polyalkylene oxide (A) having a number average molecular weight (Mn) of 20,000-50,000 and a molecular weight distribution (Mw/Mn) of 1.2 or less and having a hydrolyzable silyl group; a hydrated metal compound (B); an aminosilane compound (C); a silanol condensation catalyst (D); and a plasticizer (E). The content ratio of the hydrated metal compound (B) to the plasticizer (E) [the mass of the hydrated metal compound (B)/the mass of the plasticizer (E)] is 1.8-7.SELECTED DRAWING: None 【課題】本発明は、難燃性を有しながら、硬化後に優れたゴム弾性を長期間に亘って維持することができる硬化性組成物を提供することを目的とする。【解決手段】本発明の硬化性組成物は、数平均分子量（Ｍｎ）が２００００〜５００００であり且つ分子量分布（Ｍｗ／Ｍｎ）が１．２以下である加水分解性シリル基を有するポリアルキレンオキサイド（Ａ）、水和金属化合物（Ｂ）、アミノシラン化合物（Ｃ）、シラノール縮合触媒（Ｄ）及び可塑剤（Ｅ）を含み、水和金属化合物（Ｂ）と可塑剤（Ｅ）との含有比率〔水和金属化合物（Ｂ）の質量／可塑剤（Ｅ）の質量〕が１．８〜７であることを特徴とする。【選択図】なし
