PROBLEM TO BE SOLVED: To provide a wall paper excellent in emboss-processing property, air permeability and moisture permeability and capable of exhibiting the effect of an additive effectively. SOLUTION: This method for using a polybutylene terephthalate film as the wall paper is provided by installing penetrated and unpenetrated holes having 0.5-30μm mean opening diameter on the whole surface of the polybutylene terephthalate film of the wall paper obtained by laminating the polybutylene terephthalate film on a substrate, and also making≥500 holes/cm<SP>2</SP>mean distribution density of the penetrated holes.
