To provide a gauze woven fabric which has excellent opaqueness, moisture retention properties, water absorbency and comfort for skin (softness) while maintaining light weight and air permeability which are characteristic properties of gauze woven fabrics. Warps (1,2) are supplied from a first beam, and wefts (3,4) are then drawn across the warps to form a tight layer A. Warps (5,6) are supplied from a second beam that has a higher supply speed than that of the first beam, and wefts (7,8) are then drawn across the warps to form a loosened layer B. Subsequently, knotting points for connecting the layer A to the layer B regularly are formed.
