PURPOSE:To obtain functional paper useful as filter, etc., exhibiting deodorant effect in a wide temperature range from low temperature to high temperature containing specific amount of specific calcium phosphate-based compound as a filler. CONSTITUTION:10-80wt.% calcium phosphate-based compound (preferably apatite, tricalcium phosphate or tetracalcium phosphate) comprising a ratio of Ca/P=0.8-2.0, preferably 1.5-1.67 is contained in the aimed functional paper. Besides, said calcium phosphate-based compound is preferably composed of secondary particles having 0.1-30mum averaged particle diameter and made by drying or burning at 500-1300 deg.C after mixing. |
