摘要：
An adhesive composition containing, at least one solid rubber (A) selected from the group consisting of a natural rubber, a polyisoprene rubber, a polybutadiene rubber, a styrene-butadiene copolymer rubber, a styrene-isoprene copolymer rubber, an acrylonitrile-butadiene copolymer rubber, a chloroprene rubber, an ethylene-propylene rubber, and a butyl rubber, and
5 to 250 parts by mass of a liquid farnesene-based rubber (B) and 10 to 500 parts by mass of a tackifier resin (C), relative to 100 parts by mass of the solid rubber (A),
in which the liquid farnesene-based rubber (B) meets the following requirements (I) and (II):
(I) a melt viscosity measured at 38°C is in a range of 0.1 to 3,000 Pa·s; and
(II) when a measurement is performed through a gel permeation chromatography (GPC), a maximum peak-molecular weight (Mt) is 3,000 to 200,000 and a molecular weight distribution (Mw/Mn) is 1.0 to 1.4.
