A polyester woven-fabric hook-and-loop fastener comprising a woven base fabric formed of a warp yarn and a weft yarn, and a yarn for engaging elements, woven in parallel to the warp yarn of the base fabric, the yarn for engaging elements forming a number of loop-shaped engaging elements, hook-shaped engaging elements, or both that rise up from a front surface of the base fabric, each of the warp yarn, the weft yarn, and the yarn for engaging elements being of a polyester fiber, the weft yarn containing a heat-fusible fiber, the engaging elements each being fused at a root thereof to the heat-fusible fiber to thus be fixed to the base fabric, the polyester woven-fabric hook-and-loop fastener satisfying requirements and described below: the warp yarn alternately runs over and under the weft yarn with the weft yarn interposed therebetween, a selvage area having no engaging elements is present continuously in a warp direction (Wa) on each of two opposite ends parallel to the warp yarn on the base fabric front surface side, characterized in that a thickness (T b) of the warp yarn in a base fabric thickness direction at a point where the warp yarn is the most subducted toward a base fabric rear surface side is 0.94 times or less a thickness (T s) thereof in the base fabric thickness direction at a point where the warp yarn is the most floated toward a base fabric front surface side. a woven base fabric formed of a warp yarn and a weft yarn, and a yarn for engaging elements, woven in parallel to the warp yarn of the base fabric, the yarn for engaging elements forming a number of loop-shaped engaging elements, hook-shaped engaging elements, or both that rise up from a front surface of the base fabric, each of the warp yarn, the weft yarn, and the yarn for engaging elements being of a polyester fiber, the weft yarn containing a heat-fusible fiber, the engaging elements each being fused at a root thereof to the heat-fusible fiber to thus be fixed to the base fabric, the polyester woven-fabric hook-and-loop fastener satisfying requirements and described below: the warp yarn alternately runs over and under the weft yarn with the weft yarn interposed therebetween, a selvage area having no engaging elements is present continuously in a warp direction (Wa) on each of two opposite ends parallel to the warp yarn on the base fabric front surface side, characterized in that a thickness (T b) of the warp yarn in a base fabric thickness direction at a point where the warp yarn is the most subducted toward a base fabric rear surface side is 0.94 times or less a thickness (T s) thereof in the base fabric thickness direction at a point where the warp yarn is the most floated toward a base fabric front surface side. the warp yarn alternately runs over and under the weft yarn with the weft yarn interposed therebetween, a selvage area having no engaging elements is present continuously in a warp direction (Wa) on each of two opposite ends parallel to the warp yarn on the base fabric front surface side, characterized in that a thickness (T b) of the warp yarn in a base fabric thickness direction at a point where the warp yarn is the most subducted toward a base fabric rear surface side is 0.94 times or less a thickness (T s) thereof in the base fabric thickness direction at a point where the warp yarn is the most floated toward a base fabric front surface side.
