Abstract: Provided are: a conductive film which exhibits excellent flexibility and elongation over a wide range of electrical resistance change ratios; a (meth)acrylic conductive material which is able to be used as a starting material for this conductive film and has excellent usability and formability; a method for producing this (meth)acrylic conductive material; and an actuator which uses this conductive film. A (meth)acrylic conductive material which contains a (meth)acrylic elastomer and a conductive agent, and which is characterized in that: the (meth)acrylic elastomer is obtained by polymerizing a monomer component containing a (meth)acrylic monomer represented by formula (I) (wherein R1 represents a hydrogen atom or a methyl group; and R2 represents an alkyl group having 1-10 carbon atoms, which may have a hydroxyl group or a halogen atom, or an alkoxyalkyl group having 2-12 carbon atoms, which may have a hydroxyl group); and the (meth)acrylic elastomer has a weight average molecular weight of 1,200,000 to 10,000,000 and a molecular weight distribution (weight average molecular weight/number average molecular weight) of 1-6.
