Abstract
A ceramic electronic component achieves a sufficient drop resistance strength even when terminal electrodes are formed with a higher density. The ceramic electronic component includes a ceramic laminate including ceramic laminates which are laminated to each other, first terminal electrodes disposed in a peripheral portion of a bottom surface of the ceramic laminate, catch pad electrodes arranged in the ceramic laminate so as to face the respective first terminal electrodes, and sets each including at least two first via hole conductors, which electrically connect the first terminal electrodes and the respective catch pad electrodes.
Claims11
A ceramic electronic component comprising:
- a ceramic laminate including ceramic layers laminated to each other;
- at least one terminal electrode provided on a first primary surface of the ceramic laminate;
- at least one catch pad electrode arranged in the ceramic laminate so as to face the terminal electrode;
- and
- at least one set each including at least two first via hole conductors which electrically connect the terminal electrode and the catch pad electrode.
A method for manufacturing a ceramic electronic component which includes a ceramic laminate having ceramic layers laminated to each other, at least one terminal electrode provided on a first primary surface of the ceramic laminate, at least one catch pad electrode arranged in the ceramic laminate so as to face the terminal electrode, and at least one set each including at least two first via hole conductors which electrically connect the terminal electrode and the catch pad electrode, the method comprising the steps of:
- providing restriction ceramic green layers on a first primary surface and a second primary surface of a green ceramic laminate to form a green composite laminate, the green ceramic laminate being formed of ceramic green layers laminated to each other and being to be formed into the ceramic laminate, the restriction ceramic green layers being not substantially sintered at a sintering temperature of the ceramic green layers;
- firing the green composite laminate at the sintering temperature of the ceramic green layers;
- and
- removing the restriction ceramic green layers from the sintered ceramic laminate.
