A glass-resin composite of the present invention includes at least a plurality of glass sheets and a resin sheet which are integrally combined with each other via an organic resin intermediate layer, wherein, out of inner glass sheets of the plurality of glass sheets, at least one glass sheet has a crystallinity of 30% or less and a Young's modulus of 75 GPa or more.

Glass-resin composite

A glass sheet of the present invention is a glass sheet for producing a glass-resin composite through integral combination with a resin sheet, the glass sheet including as a glass composition, in terms of mol %, 40% to 80% of SiO, 5% to 30% of AlO, 0% to 20% of LiO+NaO+KO, 3% to 35% of MgO, and 0% to 15% of CaO+SrO+BaO.

Glass plate

Provided is a filler powder that has a lower coefficient of thermal expansion than silica powder and is less likely to cause quality and color alteration of a resin when blended into the resin. The filler powder is made of a crystallized glass in which &#x3b2;-quartz solid solution and/or &#x3b2;-eucryptite is precipitated. The filler powder preferably has an average particle size Dof 5 &#x3bc;m or less. The filler powder preferably has a coefficient of thermal expansion of 5&#xd7;10/&#xb0; C. or less in a range of 30 to 150&#xb0; C.
