In a crystal holding apparatus, a stepped engagement portion of a single crystal formed below a seed crystal is held by holding portions of a pair of lifting jigs so as to be pulled up. A lock mechanism consisting of a hook lever and an engagement pin is provided in order to prevent the closed lifting jigs from opening. Further, a portion of each holding portion to be contacted with a crystal is provided with a swing claw which is swingable about a horizontal pin. Accordingly, it becomes possible to reliably hold the crystal, to prevent generation of a defect in the crystal structure, and to prevent a material melt from being contaminated.
