Abstract
A step of forming a base layer on a surface on one side of a glass substrate includes a step of forming a first polyimide resin layer and a step of forming a second polyimide resin layer. The step of forming the first polyimide resin layer includes applying a first polyimide resin material while being spread in a first direction. The step of forming the second polyimide resin layer includes applying a second polyimide resin material while being spread in a second direction being a direction opposite to the first direction.
