The present invention provides an adsorbent that can be used for improving water quality and that can maintain its shape in water for a long period of time, and a method for producing the same. The adsorbent includes porous carbide, binder, iron, and at least one of carbonate and hydrogen carbonate of a metal selected from alkali metals and alkaline earth metals. The adsorbent may further include an iron compound. In the adsorbent, the porous carbide content is 20% by mass or more and 80% by mass or less, the binder content is 5% by mass or more and 50% by mass or less, and the sum of the iron and iron compound contents is 5% by mass or more and 35% by mass. % or less, and the sum of the contents of carbonate and hydrogencarbonate may be 1 mass % or more and 30 mass % or less.
