A structural member for an automobile body, comprising: a hat channel member that has a top sheet portion extending in a longitudinal direction (Z), a pair of side wall portions extending via first corner portions formed at both end portions of the top sheet portion in a width direction (X), and a pair of flange portions extending via second corner portions formed at end portions of the pair of side wall portions on sides opposite to the first corner portions ; and a joining member that has a pair of joining portions joined to the pair of flange portions of the hat channel member , and a top sheet facing portion facing the top sheet portion of the hat channel member , wherein a first bead extending in the longitudinal direction (Z) is formed on the top sheet facing portion , wherein two or more second beads extending in a direction intersecting the longitudinal direction (Z) are formed on the pair of side wall portions , wherein two or more of the first beads are formed in parallel in the width direction (X), wherein the first bead bulges inward from the top sheet facing portion in a cross section perpendicular to the longitudinal direction (Z), and wherein the first bead is formed such that a center of the first bead in the width direction (X) is positioned in a region from an inner end portion of the joining portion of the joining member to a point having a separation distance of 1/4 of a width of the top sheet facing portion in the width direction (X) in a cross section perpendicular to the longitudinal direction (Z), or wherein the first bead is formed such that a boundary point between the first bead and the joining member is positioned in a region from an inner end portion of the joining portion of the joining member to a point having a separation distance of 20 mm in a cross section perpendicular to the longitudinal direction (Z). a hat channel member that has a top sheet portion extending in a longitudinal direction (Z), a pair of side wall portions extending via first corner portions formed at both end portions of the top sheet portion in a width direction (X), and a pair of flange portions extending via second corner portions formed at end portions of the pair of side wall portions on sides opposite to the first corner portions ; and a joining member that has a pair of joining portions joined to the pair of flange portions of the hat channel member , and a top sheet facing portion facing the top sheet portion of the hat channel member , wherein a first bead extending in the longitudinal direction (Z) is formed on the top sheet facing portion , wherein two or more second beads extending in a direction intersecting the longitudinal direction (Z) are formed on the pair of side wall portions , wherein two or more of the first beads are formed in parallel in the width direction (X), wherein the first bead bulges inward from the top sheet facing portion in a cross section perpendicular to the longitudinal direction (Z), and wherein the first bead is formed such that a center of the first bead in the width direction (X) is positioned in a region from an inner end portion of the joining portion of the joining member to a point having a separation distance of 1/4 of a width of the top sheet facing portion in the width direction (X) in a cross section perpendicular to the longitudinal direction (Z), or wherein the first bead is formed such that a boundary point between the first bead and the joining member is positioned in a region from an inner end portion of the joining portion of the joining member to a point having a separation distance of 20 mm in a cross section perpendicular to the longitudinal direction (Z). <EOS>
