PURPOSE: A circuit board with guide ribs and a mounting method thereof are provided to enable a resin to be filled uniformly in a flip chip mounting structure by attaching filling guide ribs protruding from a top surface of a circuit board that is to mount a flip chip so that a resin can be filled between the flip chip and the circuit board and a filling rate varying from place to place can be controlled to be uniform by a capillary phenomenon. CONSTITUTION: A circuit board(30) comprises a circuit board body, and a plurality of board electrodes(32) formed on a top surface of the circuit board body which are to be attached to electrodes(24) protruding from a flip chip(20). The circuit board mounts the flip chip with a predetermined space therebetween. The circuit board includes at least a filling guide rib(26) protruding from a region on the top surface of the circuit board body where the board electrodes are not formed.
