<p><P>PROBLEM TO BE SOLVED: To provide a capacitor capable of preventing occurrence of a discharge phenomenon and having a high voltage resistance and a high electrostatic capacitance, and a circuit board having the same mounted thereon. <P>SOLUTION: The capacitor comprises: a capacity part 1b having a dielectric layer 5 and an internal electrode layer 7 alternately laminated, contributing to development of electrostatic capacitance; and a capacitor element 1 having a pair of covers 1c and 1d formed to hold the capacity part 1b in a direction of the lamination of the dielectric layer 5 and the internal electrode layer 7. As to the pair of covers 1c and 1d, a thickness t1 of the cover 1c arranged on an upper surface side of the capacity part 1b is different from a thickness t2 of the cover 1d arranged on a lower surface side of the capacity part 1b. An insulating material 9 is coated in the vicinity of a corner 8 of the thinner cover 1d. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
