Circuit board and method for producing same

摘要

A circuit board includes a main portion obtained by stacking a plurality of base sheets made of a flexible material in a predetermined direction and bonding the base sheets under pressure, and at least one planar conductor pattern provided in the main portion and including a concave portion and a convex portion. The concave portion and the convex portion extend in a direction perpendicular or substantially perpendicular to the predetermined direction. The concave portion is sunken in a direction parallel or substantially parallel to the predetermined direction. The convex portion protrudes in an opposite direction to the direction in which the concave portion is sunken. The at least one planar conductor pattern includes a first planar conductor pattern with a concave portion and a convex portion extending in a first direction. The circuit board further includes a plurality of first auxiliary members provided on one principal surface of the first planar conductor pattern and extending in the first direction, the first auxiliary members being spaced apart in a third direction different from the first direction.
