The present invention provides an absorbent article that allows full use of the absorption performance of an absorbent polymer, and that can be biodegraded with efficiency when it is disposed after use by burial in the soil or the like. The absorbent article includes at least one inner bag-like member, an absorbent polymer, and an outer bag-like member. The inner bag-like member is formed into a thin and substantially sheet-like form of a sheet having biodegradability and fluid permeability, and includes multiple accommodation spaces. The absorbent polymer has biodegradability and a substantially granular or powder form and is contained in each of the accommodation spaces in the inner bag-like member so as to be freely movable within the accommodation spaces. The outer bag-like member is formed of a sheet having biodegradability and fluid permeability and contains an inner bag-like member in either a layered or folded state.
