PROBLEM TO BE SOLVED: To provide a lightweight electric circuit having excellent waterproofness. SOLUTION: The electric circuit is produced by coating an electric functional component with waterproof resin dispersed with spherical bodies. When the electric functional component is coated with waterproof resin containing spherical bodies, thickness of the resin layer is made uniform by surface tension of the resin having the spherical bodies as nuclei. Since the edge part of the electric functional component can be prevented from being exposed regardless of a thin waterproof resin film, a lightweight electric circuit having excellent waterproofness can be provided.
