An assembly includes a plurality of partitions to partition an internal space, surrounded with a pair of glass substrates arranged to face each other and a the peripheral wall having a frame shape and provided between the pair of glass substrates, into an evacuation space and a ventilation space. The plurality of partitions includes a first partition and a second partition, of which lengths are defined in two different directions. An end of the second partition faces a side portion of the first partition with a predetermined gap left between them. A space between the end of the second partition and the side portion of the first partition constitutes an air passage to evacuate the evacuation space through an evacuation port. The second partition includes, at the end thereof, a swollen portion protruding toward the evacuation space at least along the width of the second partition.
