A surface mount circuit board includes: an insulating substrate having through holes each extending from front to rear surfaces of the insulating substrate; high thermal conductive members each filing a different one of the though holes; lands each disposed to cover an end surface of a different one of the high thermal conductive members and also cover part of the front surface around the peripheral edge of the corresponding through hole; and heat receiving members each disposed to cover an end surface of a different one of the high thermal conductive members and also cover part of the rear surface around the peripheral edge of the corresponding through hole. Each land may be made of solder cream filled into and flashed out of the through hole. Alternatively to the high thermal conductive members, wire rods may be fitted into the respective through holes.
