1. A refrigerator comprising:
a main body;
an ice-making chamber formed in the main body;
a refrigerant pipe in which a refrigerant flows;
an ice-making chamber fan configured to forcibly flow air in the ice-making chamber; and
an ice-making tray which stores ice-making water and generates ice,
wherein the ice-making tray includes:
a first tray having a refrigerant pipe accommodating recess which accommodates the refrigerant pipe; and
a second tray having at least one ice-making cell which stores the ice-making water, and coupled to overlap a top surface of the first tray, and
at least one heat-transfer-area-reducing [ through ] hole is formed in the refrigerant pipe accommodating recess of the first tray to decrease a heat transfer area between the first tray and the refrigerant pipe such that a cooling speed of the first tray is reduced.
