An excellent semiconductor device with high reliability is provided. [Structure] The conductive circuit 5 includes both surfaces 6a and 6b of an insulator layer 6. The conductive paths 7 and 8 are formed so as not to be exposed to the outside, and the conductive paths 7 and 8 are formed from the both surfaces 5a and 5b of the conductive circuit 5 so as to be displaced in the surface direction of the conductive circuit 5. The conductive paths 7 and 8 are connected to the bumps 9 and 10, respectively, and the conductive circuit 5 and the bumps 9 and 10 are conductive via the conductive paths 7 and 8. The bump 9 formed on one end of the one conduction path 7 of the film carrier 2 is in contact with the electrode 12 of the semiconductor element 3 and electrically connected thereto, and the film carrier 2 has the semiconductor element 3 mounted thereon. The insulating resin layer 4 is in contact with the one surface 6a of the insulator layer 6 so as to cover the semiconductor element 3. Are formed.
