A method of producing a laminated dielectric element of high quality, free of delamination. A method of producing a laminated dielectric elementby alternately laminating dielectric ceramic layersand base metal electrode layerscomprising the steps of printing electrodes by applying a paste material for the base metal electrodes onto the surfaces of at least one side of the ceramic green sheets, laminating and press-adhering the ceramic green sheets to fabricate a laminate thereof, dewaxing the laminate, reducing the electrodes to form base metal electrode layers by heating the laminate while flowing an atmospheric gas and by reducing the paste material for the base metal electrodes, and sintering the laminate. In the step of reducing the electrodes, the paste material for the base metal electrodes is so reduced that the amount of the base metal oxide remaining in the base metal electrode layers is not larger than 20% by weight and that the amount of lead liberated from the ceramic material is not larger than 30 atomic % within 5000 &#x212b; from the surfaces of the base metal electrode layers.
