    摘要: A capacitor (1) using a flexible substrate (2) includes a hole portion (6a) formed in a dielectric (6) to connect an upper electrode (7) to an external leader electrode (4). At least part of the hole portion (6a) 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 (4). Then, an upper end corner of an inclined wall surface of the upper electrode (7), which inclines along the hole portion (6a) of the dielectric (6), has a downward inclination between 0.1 and 20°. A lower end corner of the inclined wall surface of the upper electrode (7), which inclines along the hole portion of the dielectric (6), has an upward inclination between 0.1 and 20°. As a result, stress concentration on the corners of the upper electrode (7) is drastically reduced to prevent the upper electrode (7) from cracking.
