In one aspect of the present invention, a mechanical clinched joint component is a mechanical clinched joint component formed of two or more steel sheets, where the component includes at least one joint portion having a peel strength of 0.200 kN/mm or greater, and the component has a hardness of 360 Hv or greater. A method for manufacturing the component sequentially includes heating the two or more steel sheets to an Ac3 temperature or above, and performing mechanical clinch joining so that a carbon equivalent Ceq of the steel sheets, and a bottom-dead-center holding time t and a joining start temperature T during mechanical clinch joining satisfy relationships of equation (1) below and of equation (2) below: Ceq×(0.00209×t+0.000731×T−0.0365)≥0.200   (1), and Ceq≥0.00071×T+0.993   (2).
