Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a seat frame made of resin, capable of achieving both excellent cushioning property and hardness by generating stress-concentration parts as few as possible, and easy and inexpensive to mold.SOLUTION: A seat frame 1 made of resin generates deflection by a load of a person who is seated on a seat. A section close to the center of the seat frame 1 is enclosed with second resin whose rigidity is lower than that of first resin constituting the other part of the seat frame 1, and the section close to the center has a three-layered structure where a core layer 1b made of the second resin is put between upper and lower two skin layers 1a made of the first resin.
