An object of the present invention is to provide a transparent electroconductive film, which in addition to satisfying each of the requirements of favorable phototransmittance, high electrical conductivity, low refractive index and the like required when using in a multi-junction solar cell, enables running costs to be reduced since the transparent electroconductive film is produced without using a vacuum deposition method. The transparent electroconductive film for a solar cell of the present invention is provided between photoelectric conversion layers of a multi-junction solar cell, a coated film of fine particles formed by coating using a wet coating method is baked, the electroconductive component in the base material that composes the electroconductive film is present within the range of 5 to 95% by weight, and the thickness of the electroconductive film is within the range of 5 to 200 nm.
