PROBLEM TO BE SOLVED: To provide a paste-like composition capable of providing a cured product having high strength and excellent elongation.SOLUTION: The paste-like composition is provided which comprises: a calcium carbonate particle having a BET specific surface area of 5 to 60 m/g; and a paste-like polymer. In an image of a calcium carbonate particle obtained by observing, using an optical microscope, a film formed by applying the paste-like composition to a transparent film, an area ratio of an agglomerated particle having a particle diameter of 20 μm or more is 30% or less.SELECTED DRAWING: Figure 1 【課題】高い強度を有し、かつ伸びに優れた硬化物が得られるペースト状組成物を提供する。【解決手段】ＢＥＴ比表面積が５〜６０ｍ２／ｇである炭酸カルシウム粒子と、ペースト状ポリマーとを含むペースト状組成物であって、透明フィルム上にペースト状組成物を塗布して形成した膜を、光学顕微鏡を用いて観察したときの炭酸カルシウム粒子の画像において、粒子径２０μｍ以上の凝集粒子の画像の面積割合が３０％以下であることを特徴としている。【選択図】図１
