Abstract
A capacitor ( ) using a flexible substrate ( ) includes a hole portion ( ) formed in a dielectric ( ) to connect an upper electrode ( ) to an external leader electrode ( ). At least part of the hole portion ( ) extends from its lower end to upper end at an inclination between 0.1 and 20° with respect to a top surface of the external leader electrode ( ). Then, an upper end corner of an inclined wall surface of the upper electrode ( ), which inclines along the hole portion ( ) of the dielectric ( ), has a downward inclination between 0.1 and 20°. A lower end corner of the inclined wall surface of the upper electrode ( ), which inclines along the hole portion of the dielectric ( ), has an upward inclination between 0.1 and 20°. As a result, stress concentration on the corners of the upper electrode ( ) is drastically reduced to prevent the upper electrode ( ) from cracking.
