The present invention addresses the problem of providing a pellicle which has high EUV transmittance and high strength, while being not susceptible to damage by heat. In order to solve the above-mentioned problem, the present invention provides a pellicle which comprises a pellicle film that has a refractive index (n) of light having a wavelength of 550 nm of 1.9-5.0 and a pellicle frame to which the pellicle film is bonded. The pellicle film has a composition that contains 30-100% by mole of carbon and 0-30% by mole of hydrogen. The intensity ratio of the 2D-band to the G-band, namely (intensity in 2D-band)/(intensity in G-band) is 1 or less, or alternatively, the intensity in the 2D-band and the intensity in the G-band are 0 in the Raman spectrum of the pellicle film. |
