PROBLEM TO BE SOLVED: To provide a steel structure member particularly suitable to an application to an automotive body by improving an energy absorption capability at the time of rapidly deforming with a rigidity while suppressing an increase in a weight of a structure and an adhesive durability between a resin and a steel sheet. SOLUTION: The resin-poured foam steel structure member has an inner surface of a steel structure having a hollow part and electrodeposition painted and filled with any of an urethane foam, a phenol foam and a polyolefin foam therein with a compression strength of 0.5 kg/cm<2> or more. In this case, when a hard polyurethane foam using a water as a foaming agent is used, it is better. |
