Abstract
A printed circuit board includes a base insulating layer formed of a porous film. Conductor traces are formed on the base insulating layer formed of the porous film. A cover insulating layer is formed on the base insulating layer to cover the conductor traces. The porous film used as the base insulating layer has a reflectivity of not less than 50% for light of at least a part of wavelengths in a wavelength region from 400 nm to 800 nm.
