## Abstract

A method for producing an electronic component includes a step of preparing a porous base body containing a ceramic and including an inner conductor disposed in the body; and a step of impregnating the base body with a resin emulsion.

## Claims

### Claim 1

A method for producing an electronic component, the method comprising:
preparing a porous base body containing a ceramic and including an inner conductor disposed inside the base body; and
impregnating the base body with an emulsion of a resin, wherein
the resin in the emulsion has a particle size distribution having a plurality of peaks.

### Claim 2 (depends on 1)

The method according to claim 1, further comprising:
forming an outer electrode on a surface of the base body so that the outer electrode is electrically connected to the inner conductor, wherein
at least one layer in the outer electrode is formed by plating.

### Claim 3 (depends on 1)

The method according to claim 1, further comprising:
impregnating the emulsion-impregnated base body with a homogeneous resin.

### Claim 4 (depends on 1)

The method according to claim 1, further comprising:
washing, with water, the emulsion-impregnated base body.

### Claim 5 (depends on 1)

The method according to claim 1, wherein
the resin in the emulsion has a particle diameter in a range from 0.01 μm to 1 μm.

### Claim 6 (depends on 5)

The method according to claim 5, wherein
the resin in the emulsion has a particle diameter in a range from 0.01 μm to 0.5 μm.

### Claim 7 (depends on 1)

The method according to claim 1, wherein
the emulsion is at least one emulsion selected from the group consisting of an epoxy emulsion, an acrylic emulsion, a silicone emulsion, and an acrylic-silicone emulsion.

### Claim 8 (depends on 7)

The method according to claim 7, wherein
the emulsion is a silicone emulsion.

### Claim 9 (depends on 7)

The method according to claim 7, wherein
the resin in the emulsion has a particle diameter in a range from 0.01 μm to 1 μm.

### Claim 10 (depends on 7)

The method according to claim 7, further comprising:
forming an outer electrode on a surface of the base body so that the outer electrode is electrically connected to the inner conductor, wherein
at least one layer in the outer electrode is formed by plating.

### Claim 11 (depends on 7)

The method according to claim 7, further comprising:
impregnating the emulsion-impregnated base body with a homogeneous resin.

### Claim 12 (depends on 7)

The method according to claim 7, further comprising:
washing, with water, the emulsion-impregnated base body.
