PROBLEM TO BE SOLVED: To provide a substrate unit which displays only rating of an installed fuse.SOLUTION: Only "T2A" that is a rating of a fuse F1 is displayed in a master substrate 100 by installing the fuse F1 to a fuse installation position of the master substrate 100. In a cut slave substrate 200, "T3.15A" that is a rating of a fuse F2 is displayed in the fuse installation position, and "T4A" that is a rating of a fuse F3 is displayed in the fuse installation position. When installing the fuse F2, display of the "T4A" that is a rating of the fuse F3 is covered. When connecting the fuse F3, display of the "T3.15A" that is a rating of the fuse F2 is covered. In this way, by inserting the cut slave substrate 200 in a rectangular hole 150, a T2A display part 160 is removed from the master substrate 100, and the "T3.15A" that is a rating of the fuse F2 or "T4A" that is a rating of the fuse F3 is displayed. |
