R1 and R2 differ from each other.

First claim

Opening claim text (preview).

What is claimed is: 1. A circuit module comprising: a wiring structure; an electronic component arranged on an upper surface of the wiring structure; an insulating resin layer which is provided on the upper surface of the wiring structure and in which the electronic component is embedded; and a metal layer provided on a side surface of the insulating resin layer and a side surface of the wiring structure, wherein when the surface roughness of the side surface of the insulating resin layer is expressed as R 1 , and the surface roughness of the side surface of the wiring structure is expressed as R 2 , R 1 and R 2 differ from each other. 2. The circuit module according to claim 1 , wherein R 1 and R 2 satisfy the condition: R 2 >R 1 . 3. The circuit module according to claim 1 , wherein R 1 and R 2 satisfy the condition: R 1 >R 2 . 4. The circuit module according to claim 2 , wherein R 1 /R 2 ranges from 0.2 to 0.95. 5. The circuit module according to claim 3 , wherein R 1 /R 2 ranges from 1.05 to 10.5.
