The present invention provides a reusable diaper, which includes a body, an absorbent pad group, and a spacer. The absorbent pad group is detachably positioned against an inner surface of the body. The absorbent pad group comprises several absorbent pads detachably superimposed in sequence to abut against each other. The spacer is detachably disposed on the body and the absorbent pad group. The spacer has two ends that are each provided with an elastic portion. A plurality of through-holes is formed in the spacer. The disclosed diaper has the following advantages: the user only needs to discard the absorbent pads contaminated with excrement, making another uncontaminated absorbent pad the uppermost layer. In addition, with each elastic portion of the spacer, the butt skin is not in contact with the absorbent pad group, and excrement can flow into the absorbent pads through the through-holes. Further, the spacer can be replaced. Accordingly, the diaper can be used repeatedly so as to achieve efficacies of environmental protection, saving costs and sanitation.本發明為一種可使用多次之尿褲,其中包含一本體、一吸水墊組與一墊片;吸水墊組可分離地貼靠設於本體之內側面上,吸水墊組包含有數個吸水墊,各吸水墊可分離地依序疊合貼靠,墊片可分離地設於本體與吸水墊組之上,墊片之兩端分別設有一彈性部,墊片上設有數個穿透孔;其優點在於,使用者僅需將沾有排泄物之吸水墊丟棄,使另一未沾污之清潔吸水墊作為最上層;另,藉由墊片之各彈性部,使屁股之皮膚不與吸水墊組接觸,且排泄物可藉由其穿透孔流入吸水墊中,同時,墊片可替換;藉此,可多次重複使用,進而達到環保、節省支出與衛生之功效。10‧‧‧本體11‧‧‧第一連接部12‧‧‧第二連接部13‧‧‧防漏立片20‧‧‧吸水墊組30‧‧‧墊片31‧‧‧彈性部32‧‧‧防水部33‧‧‧穿透孔
