Claim:
1. A flex-rigid wiring board, comprising: a flexible substrate; a first non-flexible substrate positioned on a first side of the flexible substrate; a second non-flexible substrate positioned on a second side of the flexible substrate; a first insulation layer laminated on first surfaces of the flexible substrate and first and second non-flexible substrates; and a second insulation layer laminated on second surfaces of the flexible substrate and first and second non-flexible substrates, wherein each of the first and second insulation layers has an opening portion exposing a portion of the flexible substrate such that the portion of the flexible substrate forms a flexible section connecting non-flexible rigid sections, and at least one of the first and second non-flexible substrates includes a non-flexible intermediate substrate and a heat dissipating portion comprising a heat dissipating material having thermal conductivity which is higher than thermal conductivity of the first and second insulation layers such that the heat dissipating portion is positioned in an opening portion formed in the non-flexible intermediate substrate.
