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.

Para manter um desempenho elevado da ligação entre duas folhas de vidro pelo material do metal, para obter desse modo a tensão do gás e a força elevadas da ligação. Um painel de vidro inclui um par das folhas de vidro (1A, 1B) dispostas na oposição a se com dar forma a uma abertura (V) therebetween, as bordas periféricas das folhas de vidro opostas (1A, 1B) sendo ligado diretamente a se pelo material do metal (5); wherein ligar as caras (1Aa) nas superfícies opostas do vidro sheets (1A, 1B) para ser ligado ao material do metal (5) são trabalhados para obter uma aspereza de superfície média abaixo de 30 nm.
