Abstract
A printed wiring board includes: an insulating base material; a first conductive layer disposed on a main surface of the insulating base material in a first region and a second region defined on a plane along the main surface; a second conductive layer disposed on a main surface of the first conductive layer in the first region; and an insulating layer disposed on the main surface of the first conductive layer in the second region. The ratio of a first evaluation value E1 to a second evaluation value E2 is 0.91 or more and 0.99 or less. The first evaluation value E1 is an evaluation value of strength of a first laminated part in the first region and the second evaluation value E2 is an evaluation value of strength of a second laminated part in the second region.
