The present invention provides a novel complex lipid having a cationic functional group derived from an amino acid. Namely, the present invention provides a cationic acid amino acid type lipid represented by the following formula: wherein, R1 is a hydrocarbon group having a cationic functional group derived from an amino acid, R2 and R3 are each independently a chain hydrocarbon group, A1 and A2 are each independently a linkage group selected from the group consisting of—COO—,—OCO—,—CONH—and NHCO—, and n is an integer of 2 to 4. |
