Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a polyester-based high-strength and heat bonding conjugate fiber having a low heat shrinkage percentage, good in dimensional stability and suitable for obtaining a resin-coated fibrous structure such as a canvas scarcely causing deformation due to the lowering of adhesive strength even in use under a high-temperature atmosphere. SOLUTION: This polyester-based and heat bonding conjugate fiber is a core-sheath conjugate fiber comprising a copolyester which is a copolyester comprising a terephthalic acid component, an aliphatic lactone component, an ethylene glycol component and a 1,4-butanediol component and having 90-130 deg.C crystallization starting temperature and 130-180 deg.C melting point as a sheath component and a polyalkylene terephthalate having >=220 deg.C melting point and >=0.9 [η] as a core component in (6/4) to (9/1) core-sheath conjugate ratio. The fiber has =5 g/d strength.
