ABSTRACT:
A glass panel comprising a pair of glass plates opposed to each other with a void defined therebetween, a joining seal member for joining and sealing the glass plates at peripheries thereof, a communicating bore formed in one of the glass plates for communicating with the void and a lid member adhered to the bored glass plate having the communicating bore by a thermally meltable seal member to seal the communicating bore. The lid member is made of a material having a thermal expansion coefficient smaller than a thermal expansion coefficient of the bored glass plate. The glass panel is capable of restraining cracks and breaks from generating in the bored glass plate when the lid member is adhered to the bored glass plate by the thermally meltable seal member.
