Abstract
An object is to enable suppression of thermal leakage at a peripheral portion of a pair of glass plates disposed so as to be opposed to each other with a gap interposed therebetween. A pair of glass plates 1A, 1B are disposed so as to be opposed to each other with a gap V interposed therebetween, and a periphery sealing metal material 3 is provided which joins the pair of glass plates 1A, 1B at a peripheral portion V1 thereof so as to seal the gap V in an airtight state. The periphery sealing metal material 3 interposed between opposed inner surfaces of the pair of glass plates 1A, 1B contains, in a mixed manner, a thermal insulation material 30 having lower thermal conductivity than that of the periphery sealing metal material 3.
