Zusammenfassung:	PROBLEM TO BE SOLVED: To provide fine aggregate for cement hardened body that makes it easy to select a melting furnace slag which has been limited in usage as aggregate for cement hardened body due to problems of being difficult to obtain as a uniform product and causing sometimes an alkali-silica reaction, and thereby, that makes the melting furnace slag effectively utilizable, and also, can promote effective utilization of resources and recyling of a resource which has not been effectively utilized, and a cement hardened body that is formed by blending the aggregate for cement hardened body. SOLUTION: The fine aggregate for cement hardened body of this invention is fine aggregate which is to be blended to a cement hardened body, and which is melting furnace slag, and in the glass phase of this melting furnace slag, the containing ratios of calcium oxide (CaO) component and silica (SiO2) component are 25 to 55 mol% for the calcium oxide component and 45 to 75 mol% for the silica component.
