Abstract: Disclosed herein is a manufacturing method of a porous thermal insulation coating layer. In the manufacturing method, a porous thermal insulation coating layer having excellent close adhesion may be uniformly formed within a shorter time and the porous thermal insulation coating layer may be applied to an internal combustion engine, thereby making it possible to secure low thermal conductivity and low volume thermal capacity.
