COMPOSITE MEMBER, HOLDING DEVICE, AND BONDING STRUCTURE
To suppress the occurrence of a problems caused by thermal stress occurring at a joint even under an extremely low temperature condition.SOLUTION: A composite member includes a first member formed in a plate shape, a plate-shaped second member the main component of which is a material having a coefficient of thermal expansion different from that of the main component of the first member, and a joining portion that is disposed between the first member and the second member and joins the first member and the second member, and the joining portion includes a low thermal expansion coefficient substance having a lower coefficient of thermal expansion at -120°C than the second member, and an adhesive, and the coefficient of thermal expansion at -120°C is 2 ppm/K or more and 40 ppm/K or less.SELECTED DRAWING: Figure 2
【課題】極低温条件下においても、接合部で生じる熱応力に起因する不都合の発生を抑える。【解決手段】複合部材は、板状に形成される第1部材と、第1部材の主成分の熱膨張率とは異なる熱膨張率を有する材料を主成分とする、板状に形成される第2部材と、第1部材と第2部材との間に配置され、第1部材と第2部材とを接合する接合部と、を備え、接合部は、-120℃における熱膨張率が第2部材よりも低い低熱膨張率物質と、接着剤とを含み、-120℃における熱膨張率が2ppm/K以上40ppm/K以下である。【選択図】図2
