A method for manufacturing a molded transformer comprises the steps of forming a coil by winding concentric layers of a conductor with insulating layers interposed between the adjacent layers of the conductor and provided with insulating end members at both ends of the respective layers of the conductor, providing insulating layers on the inner and outer surfaces of a resultant structure, applying a curing accelerator to the insulating layers on the inner and outer peripheral surfaces and the insulating end members at one end of the coil, assembling a wound core in the coil to form a core-coil assembly, immersing the assembly in resin with said one end of the coil directed downward, taking out the assembly when the resin starts to gel due to the action of the curing accelerator, and then setting the resin in the coil and on the wound core.
