Abstract

See full text

In a gap retention member to be disposed between a pair of glass plates when a circumference of a gap formed between the pair of glass plates with their plate faces opposing each other is to be sealed to maintain the gap under a depressurized state, the gap retention member includes hard portions to contact the pair of glass plates respectively and a soft portion disposed between the hard portions and having a lower hardness than the hard portions, the soft portion being more susceptible to deformation based on a shearing force effective in the direction along the opposing faces of the glass plates than deformation based on a compressive force effective in a thickness direction perpendicular to the opposing faces of the glass plates.
