The present disclosure is to provide a composition comprising a refrigerant that has the characteristics of having a sufficiently low GWP, and having a coefficient of performance (COP) and a refrigerating capacity equivalent to or higher than those of R404A. The present disclosure provides a composition comprising a refrigerant, the refrigerant comprising trans-1,2-difluoroethylene (HFO-1132(E)), 1,1,2-trifluoroethylene (HFO-1123), and 2,3,3,3-tetrafluoropropene (HFO-1234yf), wherein the total concentration of the three components is 99.5 mass% or more, based on the entire refrigerant, and the three components have a mass ratio that falls within a region surrounded by a figure passing through the following 5 points in a ternary composition diagram whose three vertices represent the three components:point A (HFO-1132(E)/HFO-1123/HFO-1234yf = 42.5/1.0/56.5 mass%),point B (HFO-1132(E)/HFO-1123/HFO-1234yf = 27.1/1.0/71.9 mass%),point C (HFO-1132(E)/HFO-1123/HFO-1234yf = 1.0/30.4/68.6 mass%),point D (HFO-1132(E)/HFO-1123/HFO-1234yf = 1.0/57.0/42.0 mass%), andpoint E (HFO-1132(E)/HFO-1123/HFO-1234yf = 42.5/24.1/33.4 mass%).
