The technical scheme is that the secondary coil comprises an electrician paperboard, leads having an insulating layer and an insulation line, wherein the electrician paperboard is a cone cylinder and works as a skeleton attached by the leads having the insulating layer; the leads having the multi-turn insulating layer is evenly winded on the cone-cylindrical electrician paperboard via the insulation line; lead turn-to-turn dielectric strength can be increased by the insulating layer on the leads, so voltage resistance property of the tapered coil can be enhanced; the leads having the insulating layer can be winded by the insulation line; and the leads having the insulating layer can be evenly fixed on the electrician paperboard when holes are punched and the leads are fastened, so the secondary coil of the non-adhesive tapered high-voltage pulse transformer is manufactured. The secondary coil of the non-adhesive tapered high-voltage pulse transformer solves a problem of aerial discharge due to adhesive coating technology during the manufacturing of the present tapered secondary coil; and coil turn-to-turn insulating performance is improved and overall tapered secondary coil insulating strength is guaranteed.
