## Abstract

A ceramic electronic component includes a ceramic body having a substantially rectangular parallelpiped shape. The ceramic body includes a central portion in which first and second internal electrodes are arranged, and first and second end portions in which the first and second internal electrodes are not arranged. The ceramic electronic component satisfies Expressions (1) and (2) below: W1>T (1) W2>T (2) where T denotes the dimension of the ceramic body in a thickness direction, W1 denotes the dimension of the first end portion in a width direction, and W2 denotes the dimension of the second end portion in the width direction.

## Claims

### Claim 1

A ceramic electronic component comprising:
a ceramic body; and
a first internal electrode and a second internal electrode provided in the ceramic body and each arranged in a length direction and a width direction of the ceramic body so as to extend to lengthwise end surfaces of the ceramic body; wherein
the ceramic body includes a central portion in an approximate center of the ceramic body in the width direction in which the first and second internal electrodes are arranged, a first end portion disposed on one side of the central portion in the width direction in which the first and second internal electrodes are not arranged, and a second end portion disposed on the other side of the central portion in the width direction in which the first and second internal electrodes are not arranged; and
the ceramic electronic component satisfies Expressions (1) and (2) below:
W1>T (1)
W2>T (2)
where T denotes an overall dimension of the ceramic body in a thickness direction from an uppermost surface to a lowermost surface of the ceramic body, W1 denotes a dimension of the first end portion in the width direction, and W2 denotes a dimension of the second end portion in the width direction.

### Claim 2 (depends on 1)

The ceramic electronic component according to claim 1, wherein the first internal electrode and the second internal electrode face each other in the thickness direction of the ceramic body.

### Claim 3 (depends on 1)

The ceramic electronic component according to claim 1, further comprising:
a first external electrode provided on the ceramic body and electrically connected to the first internal electrode; and
a second external electrode provided on the ceramic body and electrically connected to the second internal electrode; wherein
the ceramic body includes a first principal surface and a second principal surface each extending in the length direction and the width direction, a first side surface and a second side surface each extending in the length direction and the thickness direction, and a first end surface and a second end surface each extending in the width direction and the thickness direction; and
the first external electrode and the second external electrode are each substantially provided on the first and second principal surfaces and a corresponding one of the first and second end surfaces among the first and second principal surfaces, the first and second side surfaces, and the first and second end surfaces.

### Claim 4 (depends on 1)

The ceramic electronic component according to claim 1, wherein the ceramic body has a substantially rectangular parallelpiped shape.
