Abstract
A printed wiring board includes: an inner insulating layer including a conductive wire; a first outermost insulating layer disposed on a first surface of the inner insulating layer; and a second outermost insulating layer disposed on a second surface of the inner insulating layer. A bending elastic modulus of each of the first outermost insulating layer and the second outermost insulating layer ranges from ¼ to ¾, inclusive, of a bending elastic modulus of the inner insulating layer. A glass transition temperature of each of the first outermost insulating layer and the second outermost insulating layer falls within ±20° C. of a glass transition temperature of the inner insulating layer.
