PROBLEM TO BE SOLVED: To provide a high-frequency circuit board which gives a small loss and is inexpensive and an array antenna equipped with the same. SOLUTION: High-frequency liner projections 2 to 4 which are formed on a high-frequency circuit dielectric board 1 to transmit high-frequency signals are formed so as to be trapezoidal in cross section, so that they can be collectively formed by a molding die. Therefore, a high-frequency circuit board which has a small loss and is inexpensive, and an array antenna equipped with the same, can be realized.
