PROBLEM TO BE SOLVED: To obtain a heat fusible conjugate fiber having a good of touch, also heat sealability and small shrinkage when fabricated into a nonwoven fabric, to provide the nonwoven fabric, and to provide an absorptive product using the fabric. SOLUTION: This fabric comprises: the core component made of a copolymer resin mainly consisting of either a polyethylene terephthalate resin or polyethylene terephthalate structure; and the sheath component made of at least one kind of olefin-based resin selected from an olefin-based binary copolymer and olefin-based ternary copolymer, and the fabric has a fineness of 0.5 to 10 deniers, a sheath-to-core ratio of (50 to 50) to (70 to 30) when volumetrically expressed and a heat shrinkage of <=10% when fabricated into a nonwoven fabric, and it further satisfies the following equation: a single fiber tenacity×sheath ratio <=2.5 (unit: g/d).
