PURPOSE:To mount components on both surfaces of a ridge part by forming a conductive circuit pattern on one side surface of a flexible base member, sticking a reinforcing sheet on the other surface, covering a circuit pattern corresponding with a flexible part with a cover-lay, and forming through holes penetrating the reinforcing sheet and the flexible base member. CONSTITUTION:A flexible base member 68 is constituted by sandwiching a copper-nonclad surface 68A between a sheet type adhesive agent 64 and a release type auxiliary material 66, and laminated on a copper-nonclad surface 50A of a ridge base member 50. A plurality of through holes 78 are formed in the region of the ridge part of a laminate 74. A cover-lay 80 is stuck so as to cover the circuit pattern 72a of the flexible part of the laminate 74. A circuit pattern 72A formed of a copper foil 72 is formed on the ridge part, and a circuit pattern 54A is formed also on the copper foil 54 of the ridge base member 50 side. Thereby components can be mounted on both surfaces of the ridge part. |
