    Abstract: A flexible circuit board includes a base material including a first surface and a second surface opposite the first surface, the base material including a conductor layer, a first insulating film covering the first surface of the base material and formed with a first opening, a first insulating member formed inside the first opening and formed with a connection port to expose the conductor layer, the first insulating member having a thermal expansion coefficient smaller than that of the first insulating film, a second insulating film covering the second surface of the base material and formed with a second opening overlapping at least a portion of the first opening in a plan view, and a second insulating member formed inside the second opening and having a thermal expansion coefficient smaller than that of the first insulating film.
