The invention provides a vehicle body frame structure which can improve the collision safety performance of a vehicle body, can reduce the weight different from the prior art, and enables the manufacturing of a frame part to be easy. And furthermore, the development of a sustainable transportation system is facilitated. A vehicle body frame structure according to the present invention is provided with a frame member (side sill outer member (12)) having a hat-shaped cross-section. Among the top surface (Sa2) and the side surface (Sb2) constituting the hat shape, the side surface (Sb2) is provided with an uneven part (3) in which convex parts (31) facing the outer side of the hat shape and concave parts (32) facing the inner side of the hat shape are alternately and continuously formed in a wave shape, and the uneven part (3) is formed in such a manner that the convex parts (31) and the concave parts (32) are alternately and continuously formed in the hat shape. The height (H1) from the side surface (Sb2) is less than or equal to the plate thickness (T1) of the frame member (side sill outer member (12)).
