TWI652235B

The present invention relates to a holder, a holder unit, and a scribing apparatus which considers a problem which a formation position of a scribing line is misaligned by moving a scribing wheel to a direction of a pin axis, and stabilizes a formation position of the scribe line; thus preventing a deviation from a desired position. The holder unit (30) comprises: a ferromagnetic scribing wheel (40), the pin axis (50) penetrating a through-hole (41) of the scribing wheel, and a holder (60) located on the same axis as a pair of maintaining parts (62a, 62b) formed in the maintaining part and having pin holes (65a, 65b) penetrated by the pin axis together. A magnet (75) pulling the scribing wheel along the direction of the pin axis is accommodated in the maintaining part (62a).
