Zusammenfassung:	To provide tobermorite type calcium silicate particle capable of exhibiting excellent deacidification and decolorization to oil such as edible oil and its manufacturing method, and an oil filter agent therewith.SOLUTION: The tobermorite type calcium particle of the present invention contains an aluminum component of 0.05 wt.% or larger and 15 wt.% or smaller in Al2O3 conversion, based on the total weight of the particle. The weight ratio of the silica component and a calcium component constituting the particle is 1.0 to 6.0 in SiO2/CaO conversion, and the BET specific surface area of the particle is 280 m2/g to 600 m2/g. The calcium silicate particles of the present invention can be used as a main component of the oil filter, for example, in regenerating used edible oil.SELECTED DRAWING: Figure 1 【課題】食用油などの油脂に対して優れた脱酸性および脱色性を発揮し得る、トバモライト型ケイ酸カルシウム粒子およびその製造方法、ならびにそれを用いた油脂濾過剤を提供すること。【解決手段】本発明のトバモライト型カルシウム粒子は、粒子の全体重量を基準として、Ａｌ２Ｏ３換算で０．０５重量％以上１５重量％以下のアルミニウム成分を含有する。この粒子を構成するシリカ成分とカルシウム成分との重量比は、ＳｉＯ２／ＣａＯ換算で１．０〜６．０であり、粒子のＢＥＴ比表面積は２８０ｍ２／ｇ〜６００ｍ２／ｇである。本発明のケイ酸カルシウム粒子は油脂濾過剤の主成分として使用され得、例えば使用済みの食用油を再生することができる。【選択図】図１
