    Abstract: The present invention provides a hot melt adhesive which is less likely to cause stringing, is excellent in heat resistance and thermal stability, and has excellent adhesive strength in a wide temperature range. Moreover, the present invention provides a paper product produced by using the hot melt adhesive. Disclosed is a hot melt adhesive comprising (A) a copolymer of ethylene/olefin having 3-20 carbons and (B) a copolymer of ethylene/carboxylic acid ester, wherein the amount of the copolymer of ethylene/carboxylic acid ester (B) is from 13 to 35 parts by weight based on 100 parts by weight in total of the components (A) and (B). The hot melt adhesive is preferable when the copolymer of ethylene/olefin having 3-20 carbons (A) includes (A1) a copolymer of ethylene with octene, and the copolymer of ethylene/carboxylic acid ester (B) includes (B1) a copolymer of ethylene with methyl methacrylate.
