Abstract
There is provided a gas trapping material and vacuum heat insulation equipment where the gas trapping material can be activated in a sealing step of the vacuum heat insulation equipment, and production efficiency can be enhanced by maintaining a high gas trapping characteristic even when a gas is released in a baking step or in a sealing step under an air atmosphere. The gas trapping material contains porous metal oxide and silver particles having an average particle size of 0.5 nm to 100 nm inclusive.
