A sole structure for a sports shoe that is lighter in weight and that can secure stability and improve resilience at the time of heel strike onto the ground. A sole structure 1 has a wavy corrugated plate 3 disposed at a heel region of the sole structure 1 and having corrugations around the heel circumferential portion. Amplitudes of the corrugations are gradually greater toward the heel circumferential edges. The sole structure 1 also has a pillar member unit 5 composed of a plurality of pillar members 51-57 formed of rubber. The pillar members 51-57 are disposed around the heel circumferential portion on the bottom surface of the wavy corrugated plate 3. The top surfaces of the pillar members 51-57 are fixedly attached to the bottom surface of the wavy corrugated plate 3. The top surfaces of the pillar members 51-57 have inclined surfaces whose heights h from the bottom surfaces are gradually lowered from the heel central portion toward the heel circumferential portion.
