1. A vacuum insulator, comprising:
a metal plate;
a glass plate arranged facing and spaced apart from the metal plate; and
a sealing structure arranged between the metal plate and the glass plate and directly contacting the metal plate and the glass plate for sealed fixing of the metal plate and the glass plate, with a vacuum cavity being defined between the metal plate and the glass plate;
wherein the sealing structure comprises a nickel-plated layer and a solder sheet; and
the nickel-plated layer is formed on an upper surface of the glass plate, the solder sheet is arranged between the nickel-plated layer and a lower surface of the metal plate and directly contacting the lower surface of the metal plate, and the sealed fixing of the metal plate and the glass plate is realized by welding the solder sheet to the nickel-plated layer and the metal plate.
