A reliable printed circuit board is provided, which has breaks reduced at a bent portion of the trace patterns. The printed circuit board is provided with the trace patterns with the bent portion that is wider in pattern width than the trace portions located near both ends of the bent portion. This allows a more area to remain on the bent portion than on the prior-art bent portion and thereby provides a highly reliable trace pattern without causing a break thereon even when a patchy portion or the like is produced by printing at the bent portion.
