A circuit device which enables easy formation of a connection part that connects wiring layers to each other, and a manufacturing method thereof are provided. In a method for manufacturing a hybrid integrated circuit device of the present invention, a first resin film is formed so as to cover a first wiring layer. Thereafter, a first through-hole is formed, which penetrates the first resin film and exposes the first wiring layer from a bottom thereof. Next, a second resin film is formed so as to fill up the first through-hole. Moreover, a second through-hole is formed in the second resin film buried in the first through-hole, and a connection part is formed.
