To provide a nonwoven fabric wall sheet having good performance by combining and complexing a fine fiber nonwoven fabric formed of a polyolefin resin or its copolymer and flame resistant paper.

The nonwoven fabric wall sheet is formed by mixing a fine fiber nonwoven fabric formed of a polyolefin resin or its copolymer and having a surface wetting index of 40 to 46 and surface treated to have at least a print on its surface, a paper material and a flame retardant, and adhesively integrating it with flame restardant paper having a METSUKE (weight) of 50 to 150 g/m2 by using a thermoplastic resin. This nonwoven fabric is a spun bonded spinning method nonwoven fabric or a melt blow spinning method nonwoven fabric.
