PROBLEM TO BE SOLVED: To provide a light belt for carriage not lowering feeding precision of carrying articles of sheets of a bill, a card, a ticket, a postcard, etc. even in the case where a using term becomes long by maintaining a constant friction coefficient even in the case where the using term becomes long and oil and water is attached on a belt back surface which is a carrier surface. SOLUTION: A carrier surface is made an irregular surface by arranging at least more than one kind of abrasive grain materials 7 grain diameters of which are more than 10μm and less than 1000μm made selectively of ceramic particles, ceramic whiskers, mineral particles and metal particles of more than three at continuous or intermittent 10 stage Moh's hardness by projecting them along an overall periphery of a belt back surface 6 to be the carrier surface.
