The present invention provides an oil-filled transformer such that desired heat-dissipation capability is achieved by the thinning of an insulation oil layer serving as a heat-insulating wall and notby installing heat-dissipation ribs to dissipate heat by convection of insulation oil, while achieving both tank size reduction and tank strength. The oil-filled transformer comprises, housed inside atank, an iron core-coil assembly assembled from an iron core and coils, and insulation oil introduced therein. The iron core-coil assembly comprises a plurality of coils respectively mounted onto a plurality of leg portions of the iron core. On a tank surface facing a site where the plurality of coils are adjacent, a recessed portion is provided extending in the axial direction of the plurality of coils and recessed toward the site where the plurality of coils are adjacent, the distance between the tank surface and the site where the plurality of coils are adjacent having been shortened. In addition, a plurality of protrusions or recesses are formed on the tank surface to broaden the tank surface area.
