wherein Ar
1
represents hydrogen atom or an aryl group having at least one iodine atom as a substituent; Ar
2
represents an aryl group having at least one iodine atom as a substituent; L
1
and L
2
independently represent a divalent bridging group of which main chain contains 6 or more carbon atoms; L
3
represents a single bond or a divalent bridging group of which main chain contains 1 to 6 carbon atoms and one oxygen atom; X represents a functional group containing at least one heteroatom, provided that, when L
3
is a single bond, X represents a functional group other than hydroxyl group. The compound can be used as a membrane component of liposomes, and the liposomes can be used as a contrast medium for X-ray radiography.
