    摘要: Problem to be solved of the present invention is to provide a hot-melt adhesive agent which is capable of applying at low temperature, has an excellent adhesiveness at low temperature, and a disposable product obtained by employing the hot-melt adhesive agent. Means for solving the problem is a hot-melt adhesive agent comprised of a thermoplastic block copolymer (A) which is a copolymer of vinyl class aromatic hydrocarbons and conjugated diene compounds, wherein the thermoplastic block copolymer (A) comprises a radial type styrene block copolymer having a styrene content of 35 to 45% by weight and a diblock content of 50 to 90% by weight, and having a viscosity at 25° C. as a 25% (by weight) toluene solution of not more than 250 mPa·s (A1).
