PROBLEM TO BE SOLVED: To provide an article storage member which exhibits excellent lightness and excellent sound absorbency of high frequency sound.SOLUTION: An article storage member for an automobile is formed of a formed body of thermoplastic resin foam particles and includes a recessed storage part which is opened upward. The article storage member includes a sound absorption layer arranged on at least a lower surface side and is formed of the formed body of the thermoplastic resin foam particles with communicated air gaps. Furthermore, porosity of the entire formed body of the thermoplastic resin foam particles having the communicated air gaps is 15-50%, and porosity of a surface layer part of the formed body of the thermoplastic resin foam particles with the communicated air gaps is 15% or higher.
