PROBLEM TO BE SOLVED: To obtain a hot melt adhesive having excellent adhesiveness, low melt viscosity and excellent coating workability even in using at a relatively low temperature, excellent heat stability and excellent handling workability without tackiness in manufacturing. SOLUTION: This adhesive composition is obtained by melt blending an S-B-S or S-EB-S block copolymer, an S-I-S or S-EP-S block copolymer and an S-I or S-EP linear diblock type block copolymer. Otherwise, an S-I-S or S-EP-S block copolymer and an S-B or S-EB linear block type block copolymer are melt blended. Here, S is polystyrene block, B is butadiene block, I is isoprene block, EB is hydrogenated butadiene block and EP is hydrogenated isoprene block.
