A structural improvement of a water absorbing pad body, the improvement comprising: a water absorbing layer； an adhesive layer disposed on one side of the water absorbing layer； a waterproof layer disposed on one side of the adhesive layer relative to the water absorbing layer； and a self-adhesive layer, The adhesive layer is disposed on one side of the waterproof layer relative to the adhesive layer； wherein the adhesive layer has an adhesive force greater than that of the self-adhesive layer. According to this structure, it can be effectively attached to the ground during use without causing slippage, thereby avoiding accidents such as slipping of the individual； it can be completely free from the surface of the floor, the table top or the window surface when not in use, so as not to cause residual glue. On the surface and other issues.一種吸水墊體的結構改良，此改良包括：一吸水層；一黏著層，其設置於吸水層的一面；一防水層，其設置於黏著層相對於吸水層的一面；以及一自黏層，其設置於防水層相對於黏著層的一面；其中，黏著層的黏著力大於自黏層的黏著力。依此結構，可於使用時有效附著於地面上而不致造成滑動，進而避免發生個體滑倒等意外；可於不使用時完全自如地面、桌面或窗面等表面撕離，進而不致造成殘膠於表面等問題。
