Abstract: A vehicle body 1 includes: a side sill 5 disposed along a front-rear direction X on a lateral portion of a vehicle; constraining portions 21, 22 that constrain longitudinal-direction ends of the side sill 5; and a center pillar 4 disposed along a direction intersecting the longitudinal direction. The side sill 5 has, in the front-rear direction X, an intermediate connection portion 50 to which the center pillar 4 connects at an intermediate section, and end connection portions 51, 52 connecting to the constraining portions 21, 22. The side sill 5 has a first portion 61 extending to both sides of the intermediate connection portion 50, and a second portion 62 positioned on the front end connection portion 51 side relative to the first portion 61.
