LONG FILM CIRCUIT BOARD, AND PRODUCTION METHOD AND PRODUCTION DEVICE THEREFOR

摘要

When a long film circuit board (1d) is formed by joining a plurality of flexible film substrates (1) each formed on at least one surface thereof with a circuit pattern (2), conveying spaces (4) are provided at the pair of facing ends of the flexible film substrate , at least part of the conveying space is allowed to project (15) in a direction parallel to the conveying direction of the flexible film substrate, and the projected part of the conveying space is allowed to overlap the conveying space of an adjacent flexible film substrate to be fixed.
