PROBLEM TO BE SOLVED: To provide a styrene thermoplastic elastomer composition for foam injection molding, which gives a foam body excellent in fineness and uniformity of the cells by foam injection molding; a foam body produced by foam injection molding the thermoplastic elastomer composition; and a method for producing the foam body by foam injection molding the thermoplastic elastomer composition. SOLUTION: The thermoplastic elastomer composition for foam injection molding comprises a component (A), a component (B), and a component (C). Based on 100 pts.wt. of the component A, a content of the component (B) is 5-150 pts.wt., and a content of the component (C) is 5-300 pts.wt. The component (A) is a hydrogenated product of a block copolymer comprising an aromatic vinyl compound block and a conjugated diene compound block, and has a weight-average molecular weight of 200,000 or more, the component (B) is a propylene resin with a melt flow rate of 2-300 g/10min and melt tension of 3 cN or more, and the component (C) is a mineral oil softening agent.
