PURPOSE: An inner material of cushions including pillows and a method for manufacturing the same are provided to ensure stability without deformation and air permeability. CONSTITUTION: An inner material(10) of cushions including pillows contains 45-55 wt% of loess ingredients or charcoal ingredients inputted for functionality; 30-40 wt% of polypropylene inputted to maintain a trunk structure; and 10-20 wt% of urethane inputted for elasticity. The inside of the trunk structure has a supporting structure(11) to support the inner materials. A method for manufacturing the inner material comprises: a step of uniformly mixing functional ingredients, polypropylene, and urethane; a step of mixing with loess ingredients or charcoal ingredients; a step of injecting the mixed material into a molding frame and heating and fusing; and a step of molding the inner materials.
