To provide a vacuum insulation material using a commercial laminate film to integrally form a heat insulating box body without requiring a large machining device and a machining space.

The vacuum insulation material 100 comprises a core material 10, and a gas-barrier capsule material 20 arranged over both faces of the core material 10 to cover the core material 10. The core material 10 is shaped as the box body opened at one face and developed with its side face 12 extending around a bottom face 11. The capsule material 20 includes a first capsule material 20a and a second capsule material 20b arranged on one face of the core material 10, and a third capsule material 20c and a fourth capsule material 20d arranged on the other face of the core material. The end of the first capsule material 20a and the end of the second capsule material 20b are joined to each other with thermal deposition to form a first lug portion 22a, and the end of the third capsule material 20c and the end of the fourth capsule material 20d are joined to each other with thermal deposition to form a second lug portion 22b. The core material 10 covered with the capsule material 20 has a bent portion 13 formed by compression molding.
