PROBLEM TO BE SOLVED: To provide a part-mounting structure and a method thereof to securely reinforce the component region of a flexible printed circuit board. SOLUTION: A top gold plating layer 122 and solder 140 are laminated in order on the upper surface of an opening of a top coverlay 110 in a region wherein a component 142 is electrically connected to the top surface of a signal line, and further the component is coupled to the solder, further, a bottom gold plating layer 120 is formed on the bottom surface of an opening of a bottom coverlay 100 in a ground region of the component region, and a conductive tape 130 and conductive metal 132 are laminated in order on the bottom surface of the bottom coverlay and bottom gold plating layer in the component region. The conductive tape and conductive metal are laminated to be electrically connected for reinforcement, so the resistance value of a ground part of the flexible printed circuit board is made smaller while solidity of a component mounting surface is maintained.
