PROBLEM TO BE SOLVED: To provide a hot melt adhesive allowing low temperature coating and having excellent adhesiveness to a polyolefin base material and high creep resistance, and a disposable product obtained by using the hot melt adhesive.SOLUTION: The hot melt adhesive contains a thermoplastic block copolymer (A) of a vinyl aromatic hydrocarbon and a conjugated diene compound. The thermoplastic block copolymer (A) contains the following components (A1) and (A2). (A1) is a radial type styrene block copolymer including a styrene of 35-45 wt.% and a diblock of 50-90 wt.% and having 250 mPa s of a viscosity at 25°C in a 25 wt.% toluene solution, and (A2) is a styrene block copolymer including a styrene of less than 30 wt.% and having more than 250 mPa s of a viscosity at 25°C in a 25 wt.% toluene solution. |
