PROBLEM TO BE SOLVED: To provide a high frequency circuit board which obtains a higher gain than the conventional high frequency circuit board without increasing the area of the board. SOLUTION: The high frequency circuit board 1 comprises a radiation element board 3 having a plurality of radiation elements 2 on the upside, a power distribution line board 7 laminated on the underside of the radiation element board 3 through a first grounding conductor 5a with a power distribution line 6 formed in the interior, a high frequency line board 8 laminated on the underside of the power distribution line board 7 through a second grounding conductor 5b with a high frequency line 9 formed on the underside for electrically connecting electronic components 11 thereto, a first transmission conductor 4a for electrically connecting the radiation elements 2 to the power distribution line 6, and a second transmission conductor 4b for electronically connecting the high frequency line to the power distribution line 6. A feed point electrically connected to the first transmission conductor 4b in the radiation elements 2 is located eccentrically in a direction from the center of gravity of the radiation elements 2, and a projective member 10 is provided on an eccentric-direction side part of the upside of the radiation element board 3.
