To provide a refrigerator that uses a vacuum heat insulating material and a liquid foam heat insulating material as a heat insulating material, and prevents a space in which no heat insulating material is filled from occurring to obtain a high heat insulation effect.
A refrigerator comprises a heat insulation box body 3 formed into a box shape with a plurality of plate-like bodies, and a plurality of doors formed of plate-like bodies closing an opening of a front face of the heat insulation box body 3. A plate-like body 6 has an outer plate 31 and an inner plate 32 between which a vacuum heat insulating material 35 and a liquid foam heat insulating material 36 are filled. The vacuum heat insulating material 35 is formed into a plate shape and is provided in its surfaces with recessed grooves 35a in a lattice shape for reducing flow resistance of the liquid foam heat insulating material 36.
