A panel joint structure comprising: a first panel body portion that configures a body portion of a first panel a first joint portion that is formed on an end portion of the first panel is offset toward one side of the first joint portion in a plate thickness direction of the first panel with respect to the first panel body portion and has a first joint surface that extends along a centerline that passes through a plate thickness direction center of the first panel body portion a pair of first load transfer portions (24, 25) that are formed via bent portions (31, 32, 33, 24) on an end portion of the first joint portion at a first panel body portion side and an end portion of the first joint portion at an opposite side of the first panel body portion side and have first load transfer surfaces (24A, 25A) that are bent with respect to the first joint surface and are contained in a range of a plate thickness of the first panel body portion a second panel body portion that is positioned on the opposite side of the first panel body portion side with respect to the end portion of the first panel, extends along the centerline, and configures a body portion of a second panel; a second joint portion that is formed on an end portion of the second panel, is offset toward the opposite side of the first joint portion with respect to the second panel body portion, and has a second joint surface that is joined by welding and adhesion to the first joint surface; and a pair of second load transfer portions (44, 45) that are formed via bent portions (51, 52, 53, 54) on an end portion of the second joint portion at a second panel body portion side and an end portion of the second joint portion at an opposite side of the second panel body portion side and have second load transfer surfaces (44A, 45A) that are bent with respect to the second joint surface and are contained in a range of a plate thickness of the second panel body portion, with the second load transfer surfaces (44A, 45A) being respectively joined by adhesion to the first load transfer surfaces. (24A, 25A). a first panel body portion that configures a body portion of a first panel a first joint portion that is formed on an end portion of the first panel is offset toward one side of the first joint portion in a plate thickness direction of the first panel with respect to the first panel body portion and has a first joint surface that extends along a centerline that passes through a plate thickness direction center of the first panel body portion a pair of first load transfer portions (24, 25) that are formed via bent portions (31, 32, 33, 24) on an end portion of the first joint portion at a first panel body portion side and an end portion of the first joint portion at an opposite side of the first panel body portion side and have first load transfer surfaces (24A, 25A) that are bent with respect to the first joint surface and are contained in a range of a plate thickness of the first panel body portion a second panel body portion that is positioned on the opposite side of the first panel body portion side with respect to the end portion of the first panel, extends along the centerline, and configures a body portion of a second panel; a second joint portion that is formed on an end portion of the second panel, is offset toward the opposite side of the first joint portion with respect to the second panel body portion, and has a second joint surface that is joined by welding and adhesion to the first joint surface; and a pair of second load transfer portions (44, 45) that are formed via bent portions (51, 52, 53, 54) on an end portion of the second joint portion at a second panel body portion side and an end portion of the second joint portion at an opposite side of the second panel body portion side and have second load transfer surfaces (44A, 45A) that are bent with respect to the second joint surface and are contained in a range of a plate thickness of the second panel body portion, with the second load transfer surfaces (44A, 45A) being respectively joined by adhesion to the first load transfer surfaces.
