摘要：

A circuit substrate includes a core substrate, a reinforcing dielectric layer that is provided on one surface of the core substrate, a first electromagnetic band gap structure that is provided on one surface side of the reinforcing dielectric layer and reduces electromagnetic noise in a predetermined first frequency propagating through the core substrate, and an auxiliary pattern that is formed at a predetermined distance from an outer circumference of a pattern which forms the first electromagnetic band gap structure.
