This capacitor is manufactured, for example, as follows. That is, first, a green sheet (excluding the first protective part) whose main component is a hepteramic powder having a thickness of 100 to 200 .mu.m and having a predetermined pattern of internal electrodes on its surface is placed in a mold. And inside 1 of the predetermined pattern on 1 side! A plurality of green sheets (ceramic layers) each consisting mainly of ceramic powder having a wall thickness of 30 to 60 μm are sequentially housed in a mold. Further, a green sheet (Second Horeibukai) having a wall thickness of 100 to 200 μm and consisting entirely of ceramic powder as a main component is deposited and laminated. In this state, press the entire green sheet with the suppressor and press the green sheet and internal electrodes. -Become one. Next, the entire adhesive layer of this laminate was attached to a resin sheet, and the resin sheet was completely fixed.Then, the laminate was cut vertically and horizontally with a cutter to form chips. Next, this chip is completely peeled off from the resin sheet and placed on a firing center containing all the powder such as zirconia. Thereafter, the chip is completely fired and external electrodes are formed on both ends of the chip to obtain a laminated ceramic capacitor.

By the way, after cutting the laminate, the chips are peeled off by resin sorting, but because the chips are extremely small, it takes a lot of man-hours to peel them off from resin sorting.
The supply to the firing setter cannot be carried out smoothly.

Furthermore, when the chip is peeled off from the all-W fat sheet, the adhesive tends to adhere to the chip. For this reason, when arranging the chips in the setter for completely firing the chips, the chips stick to each other.
There is also the problem that the efficiency of the alignment work is significantly reduced.

The features of the present invention include the step of integrating all green sheets containing baking powder as the main component on the back side of the laminate including a plurality of green sheets containing ceramic powder as the main component, and the step of cutting the laminate into one piece. The first step is to cut the green sheets into dice to prevent them from being separated, and the second step is to place the green sheets together with all the chips in the center and bake them. .

According to this invention, since the bedding powder particle sheet is integrated on the back side of the laminate, the laminate will not be separated into pieces even if the laminate 1 is completely cut into chips using all the cutters. It never happens. For this reason, the stacked body can be easily formed into chips.
