Provided is a reinforcing film with separator, having a reinforcing film and a separator and being capable of: suppressing peeling electrostatic charge that can occur when peeling away the separator; and reducing damage to an optical member or an electronic member, even when peeling the separator from the reinforcing film with separator that has been pasted beforehand on to a exposed surface side of the optical member or electronic member, etc. This reinforcing film with separator has a reinforcing film P and a separator Q. The reinforcing film P includes a base material layer A1 and an adhesive layer A2. The separator Q includes a release layer B1 and a base material layer B2. The adhesive layer A2 and the release layer B1 are directly laminated. The peeling electrostatic potential of a surface of the adhesive layer A2 is no more than 5.0 kV, when the separator Q is peeled away from the reinforcing film P at a temperature of 23 DEG C, a relative humidity of 50%RH, a peeling angle of 150 DEG, and a peeling sp
