Abstract: A clearance narrowing material containing a brush-shaped polymer chain aggregate formed of multiple polymer chains immobilized on a substrate. The invention provides a clearance narrowing material which can effectively prevent fluid leakage through a clearance and which does not disturb relative movement of members to form a clearance, and can realize an article in which fluid leakage through a clearance can be effectively prevented and the members to form a clearance can move smoothly.
