    摘要: In a circuit device of the present invention, the lower surface side of a circuit board is covered with a second resin encapsulant, and the upper surface side and the like of the circuit board are covered with a first resin encapsulant. Since heat dissipation to the outside of the circuit device is achieved mainly through the second resin encapsulant, a particle size of filler contained in the second resin encapsulant is made larger than a particle size of filler contained in the first resin encapsulant. Heat dissipation to the outside of the circuit device is greatly improved.
