- FIG. 1 is a diagram for explaining the process of applying the external electrode paste 11 to the ceramic body 12 in this embodiment.

- the ceramic body 12 is pulled up (see FIG. 1(b)).
- the regions where the external electrodes are formed are, for example, both end faces of the ceramic body 12 .
- the external electrode paste applied to the ceramic body 12 is denoted by 11a.
- the coating amount of the external electrode paste is smaller at the end part, and the gas-liquid interface per volume at the end part is larger. For this reason, drying progresses more easily at the ends. Therefore, the ratio of the solid content (resin and metal filler) in the external electrode paste is higher in the end portion than in the center portion. As a result, the solid-liquid interface increases at the edge relative to the center, making the edge energetically unstable.
- the first solvent preferentially volatilizes. For these reasons, the solvent moves from the central portion to the end portions so that the concentration gradient of the solid content in the external electrode paste is relaxed. Also, convection of the solvent from the center to the ends is generated so that the composition of the solvent is homogenized.
- the solvent moves so that the composition of the solvent becomes uniform during the process of drying the external electrode paste 11a on the ceramic body 12. .
- This solvent movement serves to promote outward flow. Due to the strong outward flow, the external electrode paste 11a flows from the central portion to the end portions. Therefore, it is possible to prevent the external electrode paste 11a from swelling outward in the central portion (see FIG. 1(d)).
- the external electrode paste in the present embodiment contains predetermined amounts of the above-described second solvent and first solvent as solvents, and therefore has better fluidity than conventional external electrode pastes.
- the use of the external electrode paste according to the present embodiment can suppress swelling of the center portion compared to the end portions. Therefore, an electronic component manufactured using the external electrode paste in this embodiment is miniaturized.

- the shape of the external electrode 22b formed using the conventional external electrode paste is a convex shape with a thick central portion and thin end portions.
- the shape of the external electrode 22a formed using the external electrode paste in the present embodiment is a flat shape in which swelling at the central portion is suppressed. Therefore, by forming the external electrodes using the external electrode paste of the present embodiment, the size of the multilayer ceramic capacitor can be reduced. In addition, when compared with the same size, the external electrodes can be made thinner and the internal elements can be made larger, so that the capacity can be increased.
- the method of applying the external electrode paste to the ceramic body in this embodiment is not limited to the immersion in the external electrode paste described above.
- the external electrode paste described above can be used when forming external electrodes of electronic components, such as multilayer ceramic capacitors.
