The invention provides a cinnamic acid derivative having a novel spacer introduced into cinnamic acid which is photodimerizable, a cinnamic acid-polymer derivative photocurable with high sensitivity and efficiency obtainable by introducing the above cinnamic acid derivative into a host polymer such as a glycosaminoglycan, and a photocrosslinked cinnamic acid-polymer derivative obtainable by exposing the same cinnamic aicd-polymer derivative to ultraviolet light irradiation.
