Abstract

PURPOSE:To make it possible to improve a flexing characteristics and to obtain a dust-free double-side flexible printed circuit board (FPC) by the absence of the bonding agent in the flexing section. CONSTITUTION:A surface copper circuit 4 is totally laminated to the surface of a base film 1 via a surface bonding agent layer 2, and on the rear of the base film 1, while a rear copper circuit 5 is laminated via a rear bonding agent layer 3 to the non-flexing section in which a throughhole is drilled, for instance. In the part becoming the flexing section, the base film 1 per se is exposed, and only the part of the rear copper circuit 5 is covered with a film cover-lay 7' through a bonding agent 8' for the film cover-lay, with the remaining part being covered with a film cover-lay 7 through a bonding agent 8 for the film cover-lay. With this set-up, there is no dust generated due to a bonding agent or the like, and a double-side FPC rich in the flexing characteristics is obtained.
