Zusammenfassung:	PURPOSE:To improve mechanical strength of a circuit board by securing a metal plate shaped along the surface shape of a dielectric board as a ground conductor on one side surface of the dielectric board made of resin or mixture of resin and inorganic material and varying in thickness. CONSTITUTION:A metal plate 8 molded along the surface shape of a dielectric board 2 is secured as a ground conductor on the substantially whole surface of one side nonflat surface of the board 2. In the circuit board, the plate 8 as the ground conductor is operated to reinforce the board 2. Accordingly, such a board is strengthened against a mechanical stress such as vibration, etc. Accordingly, it is adapted for a circuit board of a mobile communication apparatus, a plane antenna, etc.
