When the door body 10 is manufactured, the foaming liquid is filled between the door shell 100 and the door liner body 210 and between the foaming liquid and the sealing part 220, the foaming liquid forms the foaming layer after foaming and curing, and the foaming layer can improve the heat preservation capability of the door body 10 and can also improve the overall strength of the door body 10. The door 10 is used for sealing a refrigerator body, and the sealing portion 220 is formed with a cavity 221 recessed in a direction away from the door shell 100, so that a portion of the foaming layer located in the cavity 221 is closer to the refrigerator body than a portion located between the door shell 100 and the door liner body 210. During refrigerator refrigeration, the foaming layer is located part in the cavity 221 receives microthermal influence in the box more easily and leads to shrinkage deformation, the foaming layer is close to the part of door shell 100 more is close to external environment temperature, receives refrigerator refrigeration microthermal influence less.
