    Abstract: PROBLEM TO BE SOLVED: To provide a thermal bonding conjugate fiber with excellent compression resistance and nonwoven fabric using the same, more specifically, a thermal bonding conjugate fiber and nonwoven fabric using the same, in which the bulkiness of the nonwoven fabric under a light load is retained well even under a heavy load, and the rate of decrease in bulkiness between under a light load and under a heavy load can be reduced. SOLUTION: The thermal bonding conjugate fiber with thermal shrinkage properties has an eccentric core-sheath structure in which a first component comprising a polyester resin constitutes a core and a second component comprising a polyolefin resin having a melting point at least 15°C lower than a melting point of the polyester resin constitutes a sheath, and a shrinkage ratio after a heat treatment of 120°C is at least 20% when calculated by a predetermined measurement method. The nonwoven fabric is obtained by blending the thermal bonding conjugate fiber with one or more types of other thermal bonding fibers, and the thermal bonding conjugate fiber is contained therein at a blend ratio of 10 to 60 mass%.
