Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an adsorbent which is manufactured at a low manufacturing cost by using waste casting sand while dispensing with a firing step and exhibits excellent adsorptivity to organic matter, ammonia gas or a heavy metal ion and to provide an adsorbent-granulated material. SOLUTION: The method for manufacturing the adsorbent comprises: a solid removing step S1 of collecting waste casting sand discarded from a foundry and removing impurities by a screen to sort waste casting sand having
