To provide a polymerizable composition that can produce a molding that is easily repaired when damaged and has high hardness, and provide a molding that is easily repaired when damaged and has high hardness.SOLUTION: A polymerizable composition has a polymerizable compound (A) and a metal ion (B). In the polymerizable compound (A), the proportion of a component (a) is 50 mol% or more and 100 mol% or less, the component (a) having a solubility parameter equal to or higher than a first value and equal to or lower than a second value, which is higher than the first value by 2.0. The first and second values are defined so that the proportion becomes the largest. The component (a) contains at least unsaturated carboxylic acid (a1).SELECTED DRAWING: Figure 1 【課題】傷がついても修復されやすく、かつ高い硬度を有しうる成形体を作製できる重合性組成物、及び傷がついても修復されやすく、かつ高い硬度を有しうる成形体を、提供する。【解決手段】重合性組成物は、重合性化合物（Ａ）と金属イオン（Ｂ）とを含有する。重合性化合物（Ａ）中の、溶解度パラメータが第一の値以上であり、かつ前記第一の値よりも２．０大きい第二の値以下である成分（ａ）の占める割合が、５０モル％以上１００モル％以下である。第一の値及び第二の値は、前記の割合が最大になるように規定される。成分（ａ）は、少なくとも不飽和カルボン酸（ａ１）を含有する。【選択図】図１
