It is.

A method of manufacturing the multilayer ceramic capacitor having the above configuration will be described. In laminating a plurality of ceramic green sheets formed of a slurry containing barium titanate as a main component to a predetermined thickness to form the ineffective layer 10, a thickness between the lower surface and the lower surface in the laminating process is 80 μm or less. A reinforcing electrode 17 containing silver or nickel as a main component is formed by printing, and an internal electrode layer 11 also containing silver or nickel as a main component is printed on the ineffective layer 10. An effective layer 12 made of a green sheet is laminated, and an internal electrode layer 13 is formed thereon.
Is printed, then the steps of printing the internal electrode layer 11, laminating the ceramic green sheets of the effective layer 12, and printing the internal electrode layer 13 are repeated a plurality of times.
The ineffective layer 14 on which the reinforcing electrode 17 is printed is laminated and fired at the following positions, and the internal electrode layers 11 and 13 and the reinforcing electrode 17 are exposed at both end surfaces of the sintered laminate 15. External electrodes 16 made of silver or the like were formed on the upper and lower surfaces and the front and rear surfaces adjacent to both end surfaces, and nickel plating and Sn-Pb plating were performed on silver as the external electrodes 16 to obtain a multilayer ceramic capacitor.

This laminated ceramic capacitor has a length of 3.2 mm, a width of 1.6 mm, and a thickness of 0.85 mm.
mm, the length of the laminate 15 excluding the external electrodes 16 is 3.1 mm in the length direction, 1.5 mm in the width direction, 0.81 mm in the thickness direction, and has a capacitance of 0.1 μF, Tan δ 1.5%, and insulation resistance. 1x
It was 10 11 Ω.

As a comparative example, the thickness of the inactive layer having the same shape, the same capacitance, Tan δ, and insulation resistance as those of the second embodiment and having no reinforcing electrode is set to 100 μm, 120 μm,
A multilayer ceramic capacitor having a size of 140 μm was prepared.

Using these multilayer ceramic capacitors of the present invention and the comparative example, the results of measuring the bending strength due to the bending of the mounting board are shown in Table 1.

[0025]

[Table 1]

The bending strength is determined by mounting a multilayer ceramic capacitor on a mounting board having a thickness of 1.6 mm, and gradually bending the mounting board by 0.2 mm, thereby lowering the capacitance of the multilayer ceramic capacitor. The amount of deflection immediately before was expressed as bending resistance due to deflection of the mounting board.

As is clear from Table 1, when the thickness of the inactive layers 10 and 14 between the external electrode 16 and the reinforcing electrode 17 is set to 80 μm or less, the bending resistance due to the bending of the mounting board is remarkably improved. You can see that

When the invalid layers 10 and 14 are formed to be thick, as shown in FIG. 3, a plurality of reinforcing electrodes are provided on the internal portions of the invalid layers 10 and 14 facing the lower surface or upper surface of the external electrode 16. By forming 17, the bending strength due to the bending of the mounting board can be further improved. Also in this case, the thickness of the inactive layers 10 and 14 between the external electrode 16 and the reinforcing electrode 17 and between the reinforcing electrodes 17 is 80.
The condition is that the thickness be equal to or less than μm.

In FIGS. 2 and 3, the reinforcing electrode 17 is electrically connected to the external electrode 16, and the stray capacitance due to the reinforcing electrode 17 is eliminated to stabilize the characteristics. As shown in FIG. 4, the reinforcing electrode 17 is separated from the external electrode 16, that is, even if the reinforcing electrode 17 is not formed up to the end face on which the external electrode 16 is formed, the reinforcing electrode 17 and the external electrode 16 can be separated. Invalid layer 10,
By setting the thickness of 14 to 80 μm or less, the bending resistance due to the bending of the mounting substrate can be improved, and the reinforcing electrodes 17 can be formed roughly, which is advantageous in terms of productivity.

As shown in FIGS. 5 and 6, the outermost layer 11a of the internal electrode layer 11 is provided at the portion of the external electrode 16a connected to the internal electrode 13 facing the capacitor, particularly in a capacitor used for medium and high voltage applications. The outer electrode 13a of the internal electrode layer 13 is formed so as not to overlap with the provided reinforcing electrode 17a in the thickness direction.
It is desirable to form the reinforcing electrode 17b provided in the portion 6b so as not to overlap in the thickness direction. Thereby, the bending strength can be improved, and the withstand voltage and the starting voltage of creeping discharge generated between the external electrodes on the surface can be increased.

More specifically, for example, the inner electrode layer 13 is formed so as not to overlap in the thickness direction with the reinforcing electrode 17b provided at the portion of the outer electrode 16b connected to the inner electrode 11 opposed to the outermost layer 13a. 13 outermost layer 13a
The withstand voltage and the starting voltage of creeping discharge can be increased as the distance between the electrode and the reinforcing electrode 17b is increased. However, when the length of the outermost layer 13a is less than half the total length of the laminate, the effect is reduced and the capacitance is also reduced.
The length of 3a is preferably about half of the total length of the laminate.

Also, for example, the outermost layer 13 of the internal electrode layer 13
By increasing the distance between the reinforcing electrode 17b provided at the portion of the external electrode 16b connected to the internal electrode 11 facing the internal electrode 11a, the number of layers of the reinforcing electrode 17b can be increased as shown in FIGS. Therefore, the bending strength can be further improved. In FIG. 6, unlike FIG. 5, the reinforcing electrodes 17a and 17b are formed in a state separated from the external electrodes 16a and 16b.
Even if the distance between the outermost layer 13a and the reinforcing electrode 17b is closer than in the case of FIG. 5, the withstand voltage and the starting voltage of the creeping discharge can be increased. Further, in FIGS. 5 and 6, the outermost layers 11a and 13a of the internal electrode layers 11 and 13 are formed so as to be connected to different external electrodes, but may be formed so as to be connected to the same external electrode.

In each of the above-described embodiments, the structure in which the invalid layers 10 and 14 are provided on the upper and lower surfaces has been described. However, this is to eliminate the vertical direction during mounting. If there is no problem, a configuration in which only the ineffective layer 10 is provided only on the lower surface may be adopted.

Further, in the above embodiment, the multilayer ceramic capacitor has been described as an example. However, other multilayer ceramic components such as a multilayer varistor and a multilayer thermistor may have excellent bending strength by adopting a similar configuration. It can be.

[0035]

As described above, since the multilayer ceramic component of the present invention is constructed, the bending resistance due to the bending of the mounting board is improved. In other words, those that are easily cracked by bending in the inactive layer near the end of the lower surface portion of the external electrode,
The fragile ineffective layer is reinforced by the viscoelasticity of the internal electrode layer or the reinforcing electrode, whereby cracking due to bending can be prevented, and high reliability can be achieved.
