Single crystal production apparatus and single crystal production method

Abstract

A single crystal production apparatus (and a single crystal production method) is configured to produce a single crystal by approaching a raw material M gripped by a raw material grip portion, and a seed crystal S gripped by a seed crystal grip portion by disposing the raw material grip portion and the seed crystal grip portion mutually in a vertical direction and approaching both of them each other, and forming a melting zone M1 by making a portion melted by heating the raw material M by a heating part in contact with the seed crystal S, and cooling the melting zone, wherein the heating part has an infrared generating part, and the seed crystal grip portion is disposed at a vertically top position, and the raw material grip portion is disposed at a vertically bottom position.
