The invention relates to a production method of a thick-electrode conductor device, and the production method comprises the following steps of (1) producing a screen mesh with patterns; (2) printing electrode paste; (3) aligning and laminating electrode patterns; (4) discharging glue; and (5) sintering. The screen meshes in the step (1) are two screen meshes in mirror symmetry or the screen mesh in the step (1) is one screen mesh in central symmetry, and in the step (2), the two screen meshes or one screen mesh in the step (1) is respectively printed with electrode paste on a first ceramic substrate and a second ceramic substrate. Due to the adoption of the production method of the thick-electrode conductor device, the width of the electrode is reduced while the production of a thick electrode is realized, so that the direct-current resistance of the device is effectively reduced, and the consumption of the electrode paste can be saved on the premise of guaranteeing the performance of the device.
