Electronic component and method for manufacturing electronic component

An electronic component comprising:

• a base body which includes a first end surface and a second end surface opposite to each other in a length direction, a first main surface and a second main surface opposite to each other in a thickness direction perpendicular to the length direction, and a first side surface and a second side surface opposite to each other in a width direction perpendicular to the length direction and the thickness direction, a first internal electrode exposed at the first end surface, and a second internal electrode exposed at the second surface;
• a first external electrode on the first end surface and connected to the first internal electrode;
• and
• a second external electrode on the second end surface and connected to the second internal electrode,
• wherein the first external electrode includes a first resin electrode layer containing a conductive component and a resin component,
• the first resin electrode layer of the first external electrode includes a first portion facing a whole surface of the first end surface of the base body, and
• a first plurality of protrusions are arranged periodically side by side on a surface of the first portion of the first resin electrode layer of the first external electrode, the surface of the first portion being opposite to the first end surface of the base body, and
• wherein when viewing a cross section along the length direction and the thickness direction, in the first external electrode, bottom surfaces located in respective gaps between the first plurality of protrusions and top surfaces of the first plurality of protrusions are present on a surface of the first portion of the first resin electrode layer.

A method of producing an electronic component, the method comprising:

• forming a base body which includes a first end surface and a second end surface opposite to each other in a length direction, a first main surface and a second main surface opposite to each other in a thickness direction perpendicular to the length direction, and a first side surface and a second side surface opposite to each other in a width direction perpendicular to the length direction and the thickness direction, a first internal electrode exposed at the first end surface, and a second internal electrode exposed at the second end surface;
• forming, on the first end surface of the base body, a first external electrode so as to be connected to the first internal electrode by applying a conductive paste containing a conductive component and a resin component by screen printing to form a first resin electrode layer including a first portion facing a whole surface of the first end surface of the base body so that a first plurality of protrusions are arranged periodically side by side on a surface of the first portion, the surface of the first portion being opposite to the first end surface of the base body;
• and
• forming, on the second end surface of the base body, a second external electrode so as to be connected to the second internal electrode.
