PURPOSE: A barrier film for electric components and a manufacturing method thereof can improve the performance of barrier by reducing defects from adhesion between layers and foreign objects. CONSTITUTION: A barrier film for electric components (100,200) comprises a resin film (110); an absorption layer (120) including inorganic material located on a side of the resin film, capable of being charged with positive of negative charge, and having higher hydrophilicity than the surface of the resin film; a laminated film (130) located on a side of the absorption layer, wherein at least one plate type particle layer, which includes inorganic plate type particle capable of being charged with positive or negative charge, and at least one binder layer, which is capable of being charged with positive or negative charge are laminated in turn. A manufacturing method for a electric components barrier film includes forming on a side of a resin film an absorption layer (120) including inorganic material capable of being charged with positive of negative charge, charging the surface of absorption layer with positive or negative charge, and forming on the absorption layer a laminated film laminated in turn with at least one plate type particle layer (131a,131b,131c,131d), which includes inorganic plate type particle capable of being charged with positive or negative charge, and at least one binder layer (133a,133b,133c), which is capable of being charged with positive or negative charge.
