This electromagnetic coupling structure includes a laminated body that is laminated with an inner dielectric layer interposed between inner conductive layers, one pair of outer dielectric layers facing each other with the laminated body interposed therebetween, and one pair of outer conductive layers facing each other with the one pair of outer dielectric layers interposed therebetween. The one pair of outer conductive layers include wiring portions and conductive patch portions disposed at front ends of the wiring portions, and the conductive patch portions have portions longer than the wiring portions in a direction perpendicular to an extending direction of the wiring portions. In the laminated body, a hole passing through the inner dielectric layer and the inner conductive layers is arranged, and the one pair of outer conductive layers are electromagnetically coupled through a metal film formed inside the hole.

Disclosed is a resin composition which is advantageous not only in that the resin composition can be produced at low cost, but also in that it is unlikely to thermally expand, and a prepreg, a laminate, and a wiring board formed using the resin composition. The resin composition comprises an insulating resin having an aromatic ring, wherein the insulating resin having an aromatic ring has a molecular weight between crosslinking sites of 300 to 1,000 on the stage after the production of the laminate, as determined from an elastic shear modulus of the insulating resin measured at a temperature of Tg or higher.
