Abstract: To provide a hot-melt pressure-sensitive adhesive which is easily coated, has a weak odor, high stability with time, and is also excellent in adhesive force retention performance from a low temperature range to a high temperature range. A hot-melt pressure-sensitive adhesive comprising: an amorphous polystyrene resin (A) having a number-average molecular weight of 50,000 or more; and a thermoplastic block copolymer (B) which is a copolymer of vinyl-based aromatic hydrocarbons and conjugated diene compounds.
