Abstract
This invention provides a circuit board having an electric component which has an electric element smaller than a conventional element. A circuit pattern (5) which includes a pair of contact electrodes (3, 3) is formed on the surface of a board (1) made of an insulating material. A photoresist film (7) is formed on the surface of the board (1). At least one electric element forming hole (9) is formed in the photoresist film (7) by a lithography technology so as to expose at least part of the pair of the contact electrodes (3, 3). The electric element forming hole (9) is filled with an electric element forming paste material to form an electric element (13). A protective film (15) made of a synthetic resin is so formed as to cover the electric element forming hole (9).
