There is provided a shoe sole component that has properties such as strength and cushioning property that are suppressed from being changed even under a wide temperature range from severe cold at &#x2212;10&#xb0; C. or lower to high temperature conditions exceeding 30&#xb0; C. A shoe sole component includes a cross-linked foam of a resin composition, the resin composition containing a thermoplastic polyolefin resin, in which tan &#x3b4; (&#x2212;20&#xb0; C. to 40&#xb0; C.) at a frequency of 10 Hz measured according to JIS K 7244-4 is 0.01 to 0.5, and tan &#x3b4; (&#x2212;20&#xb0; C.)/tan &#x3b4; (40&#xb0; C.) at a frequency of 10 Hz is 0.7 to 1.3.
