    摘要： A method of making a multilayer electronic component which can further improve a withstand voltage characteristic is provided. In the method of making a multilayer capacitor in accordance with the present invention, a sheet multilayer body is formed in a multilayer body forming step by laminating a plurality of electrode sheets and blank sheets formed in a sheet forming step. The sheet multilayer body is fired in a firing step, whereby a multilayer capacitor is obtained. The sheet multilayer body includes one blank sheet interposed between the electrode sheets. Namely, two green sheets are interposed between electrode patterns of the electrode sheets, whereby the green sheet thickness is substantially increased. The inventors have newly found that increasing the green sheet thickness by making the sheet multilayer body have such a structure is effective in improving the withstand voltage characteristic.
