PROBLEM TO BE SOLVED: To provide a mixed web-based wet-laid nonwoven fabric (especially thin paper for thermosensitive mimeograph) comprising natural fiber and synthetic fiber, having strength hardly torn by outer mechanical impact, simultaneously having a uniform pore distribution and permeability of fluids such as air and ink, and to provide a method for producing the same. SOLUTION: The mixed web-based wet-laid nonwoven fabric is obtained by compounding natural fiber and sulfonate-having acrylic fiber. The method for producing the mixed web-based wet-laid nonwoven fabric comprises uniformly dispersing the natural fiber and the sulfonate-having acrylic fiber in water, forming a fiber sheet, and drying.
