This shock-absorbing member comprises a molded part containing a thermoplastic resin. The molded part is provided with a main body having a honeycomb structure filled with a plurality of tubular cells. All or some of the tubular cells constituting the honeycomb structure are arrayed with cell walls interposed therebetween, the cell walls having a thickness gradient that satisfies the relationship of expression (G) and that is found by the following “method of calculating the cell wall thickness gradient”.[Method of calculating the cell wall thickness gradient]Procedure 1): set a central axis (a), which passes through one end-surface center of gravity and another end-surface center of gravity in a first tubular cell that has a height (H).Procedure 2): set any two faces (b) and (c) perpendicular to the central axis (a) within the range of the height (H) of the first tubular cell, and let the distance between the two faces (b) and (c) be h (units: mm; 0<❘"\[LeftBracketingBar]"t2-t1❘"\[RightBracketingBar]"h<250×10-4(G)
