Abstract:
Provided is a thermal insulation panel (10) as a thermal insulation structure comprising a vacuum thermal insulation material (20) and a foam thermal insulation material (13). The vacuum thermal insulating material (20) includes an outer cover (22) having gas barrier properties, a core (21) enclosed inside the outer cover (22), and a gas adsorbent (23) enclosed together with the core (21) in the outer cover (22). The inside of the outer cover (22) is in a reduced pressure state. An outer cover (22A) constituting a first surface (20a) of the vacuum thermal insulation material (20) includes a gas barrier layer (222) including at least a layered clay mineral as a filler. An outer cover (22B) constituting a second surface (20b) of the vacuum thermal insulation material (20) includes at least a gas barrier layer (224) made of metal.
