A base oil, comprising an ester compound obtained by reacting a fatty acid component and a monohydric alcohol component,
- wherein said fatty acid component includes a C4-C28 fatty acid,
- wherein said monohydric alcohol component includes at least one C4-C22 straight chain monohydric alcohol and at least one C4-C22 branched chain monohydric alcohol, a total of said C4-C22 straight chain monohydric alcohol and said C4-C22 branched chain monohydric alcohol being not less than 3,
- wherein among the total of said C4-C22 straight chain monohydric alcohol and said C4-C22 branched chain monohydric alcohol, at least one monohydric alcohol has 4 to 11 carbon atoms, at least one monohydric alcohol has 12 to 15 carbon atoms, and at least one monohydric alcohol has 16 to 22 carbon atoms,
- wherein said at least one monohydric alcohol having 4 to 11 carbon atoms is present in an amount that ranges from 0.1 wt % to 5.0 wt % based on 100 wt % of said monohydric alcohol component, and
- wherein said at least one monohydric alcohol having 16 to 22 carbon atoms is present in an amount that ranges from 0.1 wt % to 5.0 wt % based on 100 wt % of said monohydric alcohol component.
