To provide a lightweight woven fabric rich in lightweight property, excellent in soft and dry touch, resilience and firmness and having a good crepe.

This lightweight woven fabric is obtained by weaving with using a composite yarn obtained by mixing and interlacing a yarn A having ≤50 Young's modulus and ≤30% shrinkage by boiling water, and obtained by performing a heat-treatment on a highly oriented un-stretched fiber, of which main recurring unit consists of ethylene terephthalate, having a deformed cross section, 5-30% void rate and 1.3-3.5 deforming rate, with one kind, or two or more kinds of synthetic fiber multifilament yarns B having ≥1.0 denier single fiber thickness, in a part or a whole of the woven fabric, and then performing dyeing and finishing processes.
