PROBLEM TO BE SOLVED: To provide a vehicular cross member, frame structure and roof structure capable of accurately forming an installation hole or a washer at an end of the cross member or area other than the end thereof, facilitating installation on a B-pillar and attaining a highly rigid cross member shape, in a vehicular roof structure using an extruded aluminum cross member as a reinforcing material. SOLUTION: This roof structure is comprised of a cross member 11 extending in the cross direction of the vehicle and connected to upper ends of right and left B pillars and a roof panel adhesively connected to the upper surface of the cross member. A cross-sectional shape of the cross member 11 is formed with a pair of closed cross-sectional parts 12, 13 arranged on both sides at a distance between them and a wall-like rib 14 for connecting between the closed cross-sectional parts, and the pair of the closed cross-sectional parts are positioned in the longitudinal direction of the vehicle body. A bracket 18 for connecting the roof panel to the cross member 11 and a bracket 19 for connection to the B pillar are fastened to the end of the cross member 11 with bolts and nuts.
