The invention relates to an adhesive composition and an optical member surface protective film. The invention provides an adhesive composition which can form an adhesive film which enables less generation of static electricity upon peeling and less contamination to an object to be adhered. The adhesive composition herein contains methacrylic acid copolymer, ionic solid and polyether modified dimethyl polysiloxane compounds, wherein the methacrylic acid copolymer has acidic group and hydroxyl, and the ionic solid contains organic cation and a melting point of more than 25 DEG C, and the polyether modified dimethyl polysiloxane compounds have reactive group. The quantity of the ionic solid, compared with the 100 parts by mass of the methacrylic acid copolymer, is less than 0.2 parts by mass. The quantity of the polyether modified dimethyl polysiloxane compounds, compared with the 100 parts by mass of the methacrylic acid copolymer, is less than 1 part by mass.
