PROBLEM TO BE SOLVED: To provide a hot melt adhesive comprising a new aromatic block copolymer, flexible and having excellent cold resistance and adhesiveness with a high softening temperature. SOLUTION: The hot melt adhesive comprises the aromatic amide block copolymer comprising an aromatic amide unit expressed by general formula (1) and a unit selected from a group comprising a polyester, an aliphatic poly(oxyalkylene), a polycarbonate, a polyolefin, a polyorganosiloxane, a polydiene or a copolymer thereof and having 10,000-1,000,000 number average molecular weight based on the standard polystyrene measured by gel permeation chromatography.
