Abstract
A structural member is provided that includes a steel sheet with a tensile strength of 980 MPa or higher overlying another metal plate and joined thereto by welding, where a break initiating near a welded portion is less likely to be produced. A structural member () includes: a first member (), the first member being a steel sheet with a tensile strength of 980 MPa or higher; a second member () overlying the first plate (), the second member being a metal plate; a plurality of welded portions (); a plurality of heat-affected zones () each formed to surround the corresponding one of the welded portions (), the heat-affected zones having a Vickers hardness lower than that of the first member by 50 HV or more. A pair of edge sections () of the first member () are provided between adjacent heat-affected zones (). The pair of edge sections () of the first member located between the adjacent heat-affected zones () extend to cross a line (LC) linking the adjacent welded portions ().
