ABSTRACT:
The present invention provides a silica glass crucible for manufacturing a silicon single crystal, in which melt vibration can be controlled more certainly and a high yield of single crystal can be realized. A first substantially bubble-free layer10ahaving a thickness of 100 μm-450 μm is formed on the inner periphery side of an initial melt line zone10which has a height of 10 mm-30 mm, of a transparent layer, a bubble-containing layer10bhaving a thickness of 100 μm or more and bubbles with an average diameter of 20 μm-60 μm is formed outside the above-mentioned first substantially bubble-free layer10a, and a second substantially bubble-free layer10chaving a thickness of 300 μm or more is formed on the inner periphery side in the whole region lower than the above-mentioned initial melt line zone10.
