Disclosed are an assembly of a dielectric and an electrode in which an electrode is coated with a dielectric, and a method for manufacturing the same. The dielectric and electrode assembly forms a lower dielectric electrode forming the lower portion of the assembly body, sealing the lower dielectric electrode formed with the electrode and the capsule filled with the target powder, and placing the sealed capsule in the pressure vessel of the heat treatment device sintering heat treatment is applied by applying isotropic pressure, and the powder to be treated is diffusion bonded to the lower dielectric and the surface of the electrode by the sintering heat treatment to form an upper dielectric forming the upper part of the assembly body.
