Abstract
A wiring board includes: a wiring structure including: a first insulating layer; a first wiring layer formed on a bottom surface of the first insulating layer; and a protective insulating layer which covers the bottom surface of the first insulating layer and has a first opening; and a support base member bonded to the protective insulating layer with an adhesive layer and has a second opening. A diameter of the second opening at a position between the top surface and the bottom surface of the support base member in a thickness direction of the support base member is smaller than a diameter of the second opening at the top surface of the support base member and a diameter of the second opening at the bottom surface of the support base member, and smaller than a diameter of the first opening.
