To provide a reinforcement member which can reduce the weight of a vehicle body structure and which can well suppress the deformation of a vehicle body skeleton member, and the vehicle body structure provided with the same.SOLUTION: A reinforcement member is provided in the closed cross-section of a vehicle body skeleton member. When viewed from a cross-section that is orthogonal to at least either one of the lengthwise direction of the reinforcement member or a short-side direction thereof, the reinforcement member includes: an arch portion formed in an arch shape; and a load transmitting portion provided at the convex surface of the arch portion. The load transmitting portion transmits, to the arch portion, load applied to the vehicle body skeleton member.
