Abstract

An adhesively joined structure is adopted, a first member; a second member; and an adhesive layer that joins the first member and the second member to each other, in which either or both of the first member and the second member are a plated steel having a steel and a plating layer disposed on at least part of a surface of the steel, a surface of the plating layer is an uneven surface, in a cross section of the plating layer, a relationship between a length Lo of the plating layer in a longitudinal direction in an observation region of the cross section and a total length Lr of a contour line of the surface of the plating layer in the observation region satisfies the following expression (1), and at least some of the plurality of blocky binary eutectic structures or the plurality of blocky ternary eutectic structures included in the plating layer are continuously present from the surface of the plating layer to a position at 1/2 of an average thickness of the plating layer. Lr − Lo / Lo × 100 ≥ 2.0 % <img class="EMIRef" id="42d5d8ce-b274-4a02-ae50-ed90c828eab3-ia01" />
