PROBLEM TO BE SOLVED: To provide a reactor core enhancing the durability with respect to the thermal cycle of an adhesive layer, without deteriorating the static strength of the reactor core itself, and also to provide a reactor. SOLUTION: A reactor core 10 is formed of a plurality of core materials (U-shaped cores 1 and 1, I-shaped cores 2,...) having magnetism and a gap plate 3 interposed in between the adjacent core materials and having non-magnetism. In the reactor core 10, the opposing surfaces of the core materials 1 and 2 and the opposing surfaces of the gap plate 3 are fixed via an adhesive layer 4. At least one of the opposing surfaces of both the core materials 1 and 2 and the gap plate 3 is formed into a projected shape, in which the center or the substantially the center of the opposing surface is projected the most; and consequently, the thickness of the adhesive layer 4 is larger, as going toward its end portion, starting from the center or from substantially the center of the adhesive surface.
