The lubricating oil composition for a refrigerator of the present invention includes a base oil having, in a low-viscosity base oil component, polyoxyalkylene glycols that have a higher kinetic viscosity at 100°C than does the low-viscosity base oil component, wherein the base oil has a kinetic viscosity of 2.4-25 mm2/s at 100°C and a ratio (Mw/Mn) of weight-average molecular weight (Mw) and number-average molecular weight (Mn) of 1.3-13. |
