PROBLEM TO BE SOLVED: To provide a sponge, dispensing with a storage place and facilitating cleaning. SOLUTION: This sponge includes: a through hole connecting two opposite faces; and a slit containing the major axis of the through hole and connecting the through hole and the outside, whereby the sponge can be simply attached and detached to a bathroom pipe, so that the time and labor for preparing and clearing cleaning goods are saved to easily perform cleaning.
