Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a surface protective film which has excellent visibility after pasting due to high transparency, an excellent antistatic property, and an excellent adhesive property and stain resistance.SOLUTION: There is provided a surface protective film obtained by coextrusion molding comprising at least two layers of a surface layer (A) and an adhesive layer (X), where haze of the film is 8% or less and an internal haze is 4% or less, and where a surface specific resistance value of at least one of the surface layer (A) and the adhesive layer (X) at 23°C and 50% RH is less than 1×10. 【課題】高い透明性により貼付後の視認性に優れ、かつ優れた帯電防止性を有し、粘着特性や汚染性に優れる表面保護フィルムを提供する。【解決手段】共押出成形により得られた表面保護フィルムであって、表面層（Ａ）及び粘着層（Ｘ）の少なくとも２層からなる、１枚で測定したヘーズが８％以下かつ内部ヘーズが４％以下である表面保護フィルムであり、表面層（Ａ）及び粘着層（Ｘ）の少なくとも一方の層の２３℃５０％ＲＨにおける表面固有抵抗値が１?１０１３未満であることを特徴とする表面保護フィルム。【選択図】なし
