PROBLEM TO BE SOLVED: To provide a method for joining each BC/Si composite material body capable of obtaining an BC/Si composite material joined body having a hollow structure aiming at improvement of joining strength.SOLUTION: A plurality of BC/Si composite material bodies are allowed to abut together on each joining surface, and joined together by being heated at 1,000-1,385°C and held in the state where a pressure of 0.02-8.0 MPa is applied onto each joining surface under an inert gas atmosphere. |
