PROBLEM TO BE SOLVED: To provide a ventilation duct suitable for performing the press molding of nonwoven fabric, and its constituent member to enhance the formability of the nonwoven fabric when performing the press forming of a nonwoven fabric member used for the ventilation duct. SOLUTION: The constituent member 2 of the ventilation duct 1 includes the nonwoven fabric containing thermoplastic resin fiber and shaped by press working. In the constituent member, resin masses G formed by melting the thermoplastic resin fiber on a surface through a step of selectively heating the surface of the nonwoven fabric are granularly distributed on at least one surface of the nonwoven fabric, and the surface of the nonwoven fabric with the masses G distributed thereon is exposed to the surface of the constituent member 2 of the ventilation duct.
