Provided are particles that provide high detection sensitivity at the time of detecting, from a body, a measured substance such as an antigen and an antibody. The particles contain a rare earth complex and are characterized in that the polydispersity index (pdi) is 0.1 or less when the particle size distribution of the particles is measured by dynamic light scattering, and a hydrophilic polymer is present on a surface of the particles. L'invention concerne des particules qui fournissent une sensibilité de détection élevée au moment de la détection, à partir d'un corps, d'une substance mesurée telle qu'un antigène et un anticorps. Les particules contiennent un complexe de terre rare et sont caractérisées en ce que l'indice de polydispersité (pdi) est inférieur ou égal à 0,1 lorsque la distribution de la taille des particules est mesurée par diffusion dynamique de la lumière, et un polymère hydrophile est présent sur une surface des particules. 体から抗原や抗体などの測定対象物質を検出する際に、検出感度の高い粒子を提供する。希土類錯体を含む粒子であって、該粒子の粒度分布が動的光散乱による計測で、多分散指数（ｐｄｉ）が０．１以下であり、該粒子の表面に親水性ポリマーが存在している事を特徴とする。
