Chip antenna and antenna device

A chip antenna comprising:

• a dielectric substrate having a rectangular parallelepiped shape and having a bottom face, a top face, a first side face, a second side face, a third side face, and a fourth side face, the first side face and the second side face facing each other, the third side face and the fourth side face facing each other, wherein:
• the first side face and the second side face include no electrode,
• the dielectric substrate includes a first non-feeding electrode so as to extend from the fourth side face to the top face,
• the dielectric substrate includes a second non-feeding electrode that faces the first non-feeding electrode with a certain space therebetween so as to extend from the third side face to the top face,
• the bottom face includes bottom-face electrodes for the first and second non-feeding electrodes, the bottom-face electrodes electrically connected to the respective first and second non-feeding electrodes and electrically connected to respective non-feeding lines of a circuit board on which the chip antenna is mounted,
• the dielectric substrate includes a feeding electrode, the feeding electrode forming a capacitance between the feeding electrode and one of the first and second non-feeding electrodes, and
• the bottom face of the dielectric substrate includes a bottom-face electrode for the feeding electrode, the bottom-face electrode electrically connected to the feeding electrode and to a feeding line of the circuit board on which the chip antenna is mounted.
