[PROBLEM TO BE SOLVED] It enables any superior ether phospholipids to the conventional ones and a method for producing the same in an easy manner on a massive scale, in light of effects of treating and improving brain diseases such as Alzheimer's disease, Parkinson disease, depression and schizophrenia, metabolic diseases such as diabetes, various infectious diseases, and immune disorders. [SOLUTION] Ether phospholipids are obtained from bivalve tissues such as clams and corbicula by extraction processing. The ether phospholipids exhibit significantly superior effects of the above as compared to the conventional ether phospholipids derived from chicken tissues.
