Electronic circuit apparatus

An electronic apparatus comprising:

• a flexible printed circuit substrate having wiring conductors of a predetermined pattern on which electronic parts are mounted, said flexible printed circuit substrate comprising:
• a first area having mounted thereon electronic parts which generate heat,
• a second area continuous with and bent substantially perpendicular to said first area and having means for connecting an external device,
• a third area continuous with and bent substantially perpendicular to said second area and facing said first area and having mounted thereon electronic parts which are to avoid temperature rise,
• a fourth area continuous with and bent substantially perpendicular to said first area, said fourth area being spaced from and substantially parallel to said second area, and
• a fifth area continuous with and bent substantially perpendicular to said fourth area, said fifth area having connected thereto electronic parts which are to avoid temperature rise,
• a heat radiating plate disposed on an outer surface of said first area facing away from said third area, and
• a housing accommodating said flexible printed circuit substrate while covering at least a portion of said plate exposed to atmosphere.
