PROBLEM TO BE SOLVED: To provide a frame structure for a vehicle body, which efficiently improves bending resistance while suppressing an increase in the weight, and suppresses the bent deformation of a frame body near the end of a reinforcement board when the load is applied from the outside. SOLUTION: In the frame structure for the vehicle, the frame body 10 includes: a first surface to which the force in a compression direction is applied when the load is applied from the outside; a second surface to which the force in a tensile direction is applied; and a third surface positioned between the first surface and the second surface. The reinforcement board 20 includes: a base part separated from the third surface; and a plurality of convex parts projected from the base part to the third surface, and abutted with the third surface. The reinforcement board is provided in a predetermined area including part to which the load in a longitudinal direction of the frame body is applied on the third surface, and mounted on the frame body so that the strength is decreased at the end of the reinforcement board in the longitudinal direction of the frame body compared with that in the center part.
