PROBLEM TO BE SOLVED: To provide a flexible board having a structure in which the accuracy of a punching position is visually inspected when slits are punched to make easier the separation of unit circuit boards from a sheet base material. SOLUTION: In the flexible board in which slits having a plurality of connecting portions are punched, a plurality of the unit circuit boards are formed on the sheet base material 5 with its width direction assumed as X and its length direction assumed as Y, and each of the unit circuit boards is connected so that the circuit board may be easily separated from the sheet base material. The flexible board includes patterns 1, 1a, 1b, 1c, 11 to 14 at positions with a prescribed distance from the slits with regard to the X and the Y in the sheet base material, in which patterns are formed together with the circuit formation of circuits of the unit circuit boards.
