PROBLEM TO BE SOLVED: To provide a blow molding method capable of efficiently and inexpensively forming a relatively large-sized molded article having a decorative film on its surface. SOLUTION: A decorative film 5 is set to the surface of a female mold 1 on a side becoming a product surface and mold clamping is started while the inner pressure of the parison 3 ejected from a die 4 is controlled and subsequently stopped to bring the parison 3 and the decorative film 5 into contact with a mold under pressure to mold a blow molded product.
