PURPOSE: To easily use a wax lump without wasting it, and sufficiently exhibit a sliding effect.

CONSTITUTION: In wax 1 for ski to be applied to a sliding surface by melting a wax lump 3 by heat, a holding member 5 is arranged to hold the wax lump 3, and the holding member 5 is held by hand, and wax can be applied without directly touching the wax lump 3 with hand. Thereby, even when the wax lump 3 becomes small, there is no possibility of touching an iron 50, and since the wax lump 3 can be used to the end, it is not wasted. Since hot wax is applied by holding the holding member 5 by hand, a stain of the hand is not stuck to the wax lump 3, so that the stain can be prevented from being mixed in the wax.
