Problem to be solved of the present invention is to provide a hot-melt adhesive agent which is capable of applying at low temperature, excellent in adhesiveness at the wide temperature ranges (10 to 40°C), and excellent in balance between tackiness and retention force, and a disposable product obtained by employing the hot-melt adhesive agent. Means for Solving the problem is a hot-melt adhesive agent comprising 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 the following component (A1) and component (A2): (A1) a radial type styrene block copolymer having a styrene content of 35 to 45% by weight, a diblock content of 50 to 90% by weight, and has a viscosity at 25°C as 25% toluene solution of not more than 250 mPas; and (A2) a triblock type styrene block copolymer. |
