FLEXIBLE SUBSTRATE AND ELECTRIC CIRCUIT STRUCTURE

摘要

Provided is a flexible substrate wherein a short-circuit failure due to circuit pattern cutting particles generated when the flexible substrate is punched is reduced.  An electric circuit structure, which has the flexible substrate and an electric circuit substrate to which the flexible substrate is connected, is also provided.  A flexible substrate (100) has a wiring pattern (2) formed on a flexible base film (1).  The flexible substrate (100) is provided by being punched to be individually separated in a state where the wiring pattern (2) is formed on the base film (1), and the wiring pattern (2) has a small width section (2c) having a small width at an end section of the base film (1).
