Abstract
The present invention relates to a laminated member, including: a glass member having a linear transmittance at a wavelength of 850 nm of 80% or more; a bonding layer containing a resin and lying on the glass member; and a Si—SiC member lying on the bonding layer, in which the glass member includes predetermined amounts of SiO, AlO, BO, and PO, the Si—SiC member has an average linear expansion coefficient α at 20 to 200° C. of 2.85 to 4.00 ppm/° C., and has an average linear expansion coefficient β at 20 to 200° C. of 1.50 to 5.00 ppm/° C., and the laminated member has an absolute value |α-β|, which is a value obtained by subtracting β from α, of 2.00 ppm/° C. or less.
