Abstract: 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.
