<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a silicon sinterred body capable of using as a cheap raw material by a simple means. Ž<P>SOLUTION: This solid silicon sintered body is manufactured by drying a waste silicon powder in a clean environment, then the dried silicon powder is hot pressed in vacuo, at a temperature in the range of 1,150-1,300°C with a surface pressure of not less than 0.5 MPa, or this silicon sintered body is manufactured by heat treating a waste silicon powder in a hydrogen atmosphere, then the heat treated silicon powder is hot pressed at a temperature in the range of 1,150-1,300°C with a surface pressure of not less than 0.5 MPa.
