摘要：
A digital indicator (1) includes: a main body (10); a spindle (11) being axially slidable and having a contact portion (12) on one end, the contact portion abutting a to-be-measured portion; a detector (13) that detects an absolute displacement amount of the spindle (11) relative to the main body (10); and a display (14) that digitally displays the displacement amount of the spindle (11) relative to the main body (10) detected by the detector 13. The spindle (11) is slidable in a direction away from the contact portion (12) beyond the detectable range of the detector (13).
