1. A laminated member, comprising:
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, wherein
the glass member comprises, as represented by mole percent based on oxides, 55.0 mol % to 85.0 mol % of SiO2, 1.5 mol % to 22.0 mol % of Al2O3, 2.0 mol % to 14.0 mol % of B2O3, and 0 mol % to 5.0 mol % of P2O5,
the glass member has a total content of the SiO2, the Al2O3, the B2O3, and the P2O5 of 70.0% to 97.0% as represented by mole percent based on oxides,
the Si—SiC member has an average linear expansion coefficient α at 20° C. to 200° C. of 2.85 ppm/° C. to 4.00 ppm/° C.,
the glass member has an average linear expansion coefficient β at 20° C. to 200° C. of 1.50 ppm/° C. to 5.00 ppm/° C., and
the laminated member has an absolute value |α−β|, which is a value obtained by subtracting the average linear expansion coefficient β of the glass member at 20° C. to 200° C. from the average linear expansion coefficient α of the Si—SiC member at 20° C. to 200° C., of 2.00 ppm/° C. or less.
