PROBLEM TO BE SOLVED: To provide a marking device that can reliably provide marking on a sheet-like object with a laser beam emission in spite of the simple configuration thereof.SOLUTION: The marking device includes: a laser receiving roller 33 coming into contact with a sheet surface of a sheet electrode S and rotating about a rotation axis C to transport the sheet electrode S; and a laser head 51 for emitting a laser beam L to the sheet electrode S in the vicinity of the laser receiving roller 33. The laser receiving roller 33 is configured to change a distance (R1-R2) between the rotation axis C and a position of coming into contact with the sheet surface S as it rotates. |
