A method for producing a molded article having a thin film layer (B) formed on a surface of a porous body (A), the method comprising a process (I) and a process (II) described below in this order:
- process (I):
- forming the thin film layer (B) on a surface of a precursor (a) of the porous body (A) to obtain a preform, and
- process (II):
- expanding and molding the precursor (a) to the porous body (A)
- wherein in the preform obtained in the process (I), an adhesion property of the thin film (B) to the precursor (a) belongs to classes 0 to 3 in accordance with JIS K5600-5-6 (1999),
- wherein in the process (I), the thin film layer (B) is formed on the surface of the precursor (a) by wet coating, and
- wherein a content rate by volume of a void included in the precursor (a) is 10% or less by volume.
