Summary:To provide a modified fibrous wollastonite having enhanced reflectivity and a production method thereof.SOLUTION: A modified fibrous wollastonite, when subjected to surface analysis based on time-of-flight secondary ion mass spectrometry, gives the detection of Al, Fe and Si. The detection intensity ratio of Fe to Si is less than 0.13. The detection intensity ratio of Al to Si is more than 0.03 and less than 1.08. The modified fibrous wollastonite is produced by a method comprising a hydrothermal treatment of fibrous wollastonite.SELECTED DRAWING: Figure 1 【課題】反射率が向上する改質された繊維状ワラストナイト及びその製造方法の提供。【解決手段】改質された繊維状ワラストナイトは、飛行時間型二次イオン質量分析法による表面分析において、Ａｌ、Ｆｅ及びＳｉが検出され、Ｓｉに対するＦｅの検出強度比が０．１３未満であり、Ｓｉに対するＡｌの検出強度比が０．０３を超えて１．０８未満である。改質された繊維状ワラストナイトは、繊維状ワラストナイトを水熱処理することを含む製造方法で製造される。【選択図】図１
