Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an optimum configuration for adding a sound absorbing function to a sun visor whose core is blow-molded. SOLUTION: A large number of vent holes in which the diameter is ≤ 5.0 mm and the hole area ratio to be defined as the sum of the area of an opening of each vent hole to the projected area of a sun visor core is 5-30% are formed in a dispersive manner in the hollow sun visor core obtained by blow-molding thermoplastic resin, and the surface of the sun visor core is covered by an air permeable skin member.
