Abstract
A cleaning body includes a core, a foam elastic layer that is disposed to be wound around an outer peripheral surface of the core in a helical shape from one end to the other end of the core, and an adhesive layer that adheres the core and the foam elastic layer, in which a diameter of a tip portion of a cell skeleton protruding on a surface of the foam elastic layer is equal to or less than 50 μm, and in a case where an inner peripheral length of the foam elastic layer in a cross section of the core in a radial direction is X (mm) and a thickness of the foam elastic layer is Y (mm), a value of X×Y2 is equal to or greater than 45.
