Summary:To provide a propionic acid metal salt which causes dust emission at the time of use, particles of which are prevented from solidification, and which can maintain these excellent properties in good condition when a package thereof is stored for a long term.SOLUTION: Provided are propionic acid metal salt granules having an average particle diameter of 0.75-20 mm, where a content of fine powder having a particle dimeter of less than 0.500 mm as measured by a sieve test is less than 5 mass% and, even after a powdering test, a content of fine powder having a particle diameter of less than 0.500 mm is maintained at less than 5 mass%.SELECTED DRAWING: None 【課題】 使用する際に発塵が少なく、粒子の固結も防止されており、この優れた性状が包装体を長期間保管しても良好に維持できる、プロピオン酸金属塩を提供すること。【解決手段】 均粒子径が０．７５〜２０ｍｍの、プロピオン酸ナトリウム等のプロピオン酸金属塩顆粒体であって、ふるい試験で測定した０．５００ｍｍ未満の微小粒体の含有量が５質量％以下であり、粉化試験後においても、該ふるい試験で測定した０．５００ｍｍ未満の微小粒体の含有量が５質量％以下に維持されている、ことを特徴とするプロピオン酸金属塩顆粒体。【選択図】 なし
