Title:
CAPACITANCE ELEMENT AND RESONANCE CIRCUIT
Document Type and Number:
Japanese Patent JP2010258402
Kind Code:
A
Abstract:

To stably manufacture a capacitance element that suppresses capacitance variation due to misalignment of electrodes that face each other across a dielectric layer so as to have a desired capacitance.

The capacitance element is provided with: a dielectric layer 10; a first electrode 11 formed on a given surface 10a of the dielectric layer 10; and a second electrode 12 formed on a surface 10b opposite to the predetermined surface 10a of the dielectric layer 10. The first and second electrodes 11, 12 are shaped to ensure that the area of a counter electrode region between the first electrode 11 and the second electrode 12 does not vary, even if the first electrode 11 is misaligned with respect to the second electrode 12 relatively in a predetermined direction.
