Zusammenfassung:	Provided is an adhesive composition having excellent antistatic properties, corrosion resistance, and low staining property. Moreover, provided are an adhesive film using the same, and a surface protective film. The adhesive composition of the present invention contains a (meth)acrylic polymer having, as a main component, a (meth)acrylic acid ester monomer having an alkyl group with 1 to 14 carbon atoms, and also includes an ionic compound whose melting point is greater than or equal to 30°C. In addition, the adhesive composition, containing the (meth)acrylic polymer having the (meth)acrylic acid ester monomer including the alkyl group with 1 to 14 carbon atoms as the main component, contains the ionic compound in which the acid value of the (meth)acrylic polymer is 30 or less, and a melting point is 30°C or higher. 본 발명은 우수한 대전 방지 성능을 구비하고, 또한 내부식성을 가지며, 오염성이 낮은 점착제 조성물, 그것을 사용한 점착 필름 및 표면 보호 필름을 제공한다. 본 발명의 점착제 조성물은 알킬기의 탄소수가 C1∼C14인 (메타)아크릴산에스테르 모노머를 주성분으로 하는 (메타)아크릴계 폴리머를 포함하는 점착제 조성물에 있어서, 융점이 30℃ 이상인 이온성 화합물을 포함한다. 또한, 알킬기의 탄소수가 C1∼C14인 (메타)아크릴산에스테르 모노머를 주성분으로 하는 (메타)아크릴계 폴리머를 포함하는 점착제 조성물에 있어서, (메타)아크릴계 폴리머의 산가가 30 이하이고, 융점이 30℃ 이상인 이온성 화합물을 포함한다.
