A joint structure of the present invention is a joint structure between an end portion in a longitudinal direction of a hat-section member 27 that is a press-formed part of a metal sheet and another member (side sill 14), and the end portion in the longitudinal direction of the hat-section member 27 is discontinuously split into three being a bottom wall end portion 27a and two side wall end portions 27b and 27c. A width w1 of the bottom wall end portion 27a is larger than a width W of a bottom wall of a central portion of the hat-section member 27 and is welded to the another member (14). The two side wall end portions 27b and 27c are bent and welded to the another member (14). |
