Abstract
To maintain high bonding performance between two glass sheets by metal material, thereby to obtain high gas tightness and bonding strength. A glass panel includes a pair of glass sheets (1A, 1B) disposed in opposition to each other with forming a gap (V) therebetween, the peripheral edges of the opposed glass sheets (1A, 1B) being directly bonded to each other by metal material (5); wherein bonding faces (1Aa) in the opposed surfaces of the glass sheets (1A, 1B) to be bonded to the metal material (5) are worked so as to obtain an average surface roughness below 30 nm.
