회로 기판은 베이스 층, 베이스 층 상에 배치되고 내부에 공극이 정의된 회로층, 공극에 배치되고, 회로층의 열 전도율보다 낮은 열 전도율을 가진 열 차단부, 및 회로층에 실장된 전자 소자를 포함한다. A circuit board includes a base layer, a circuit layer disposed on the base layer, where an air gap is defined in the circuit layer, a heat blocking part disposed in the air gap, and an electronic element disposed on the circuit layer. The heat blocking part has a thermal conductivity lower than a thermal conductivity of the circuit layer.
