Circuit board, filter circuit using the same, and capacitance element

A capacitance element comprising:

• a circuit on a surface or inside of a circuit board and including:
• a first inductance element including a first wire that extends from a first end connected with one terminal of the capacitance element to a second end across the capacitance element;
• and
• a second inductance element including a second wire that extends from a first end connected with one terminal of the capacitance element to a second end across the capacitance element from an opposite side from the first wire;
• wherein
• in a plan view, the first wire of the first inductance element and the second wire of the second inductance element intersect with each other, and any angle defined by the first wire and the second wire is an angle other than a right angle.

A capacitance element comprising:

• a ceramic body including a plurality of laminated ceramic layers and including a pair of main surfaces that face each other and side surfaces connecting the main surfaces;
• a plurality of internal electrodes disposed inside the ceramic body;
• and
• a plurality of external electrodes disposed on the side surfaces of the ceramic body and electrically connected respectively with the plurality of internal electrodes;
• wherein
• in the ceramic body, a first functional portion and a second functional portion are disposed along a height direction connecting the pair of mutually facing main surfaces;
• the first functional portion includes:
• a first internal electrode including a linear shape and extending from a first side surface of the ceramic body to a second side surface of the ceramic body which does not face the first side surface;
