To provide a magnetic shield paint capable of forming a coating film without any gaps in a member with a complicated shape and preventing an apparatus from being shorted even when an electronic component is painted.SOLUTION: The present invention relates to a magnetic paint composition which includes binder and magnetic filler and has a surface of the magnetic filler covered with insulation film. Preferably, the surface of the magnetic filler is covered with insulation film of 10-15 nm in thickness. Preferably, the insulation film is ceramic and the ceramic is silica.SELECTED DRAWING: None 【課題】複雑な形状の部材に対して隙間のない塗膜を形成することができ、且つ、電子部品に塗装した場合であっても、機器がショートすることを防ぐができる磁気シールド塗料を提供することを目的とする。【解決手段】バインダー及び磁性フィラーを含み、磁性フィラーの表面が絶縁膜で被覆されている、磁性塗料組成物に関する。磁性フィラーの表面は厚さ１０〜１５ｎｍの絶縁膜で被覆されていることが好ましい。絶縁膜はセラミックスであることが好ましく、セラミックスはシリカであることが好ましい。【選択図】 なし
