A wavelength-converting resin composition for a photovoltaic cell, comprising: a fluorescent substance having a maximum absorption wavelength in an absorbance spectrum of which being » max (nm); resin particles; and a dispersion medium resin,
wherein a value of A 1 (»), which is represented by the following Equation 1, at the maximum absorption wavelength » max (nm) is 3.0×10 -4 (O. D. /µm) or less in a case in which:
an intensity of transmitted light that is obtained as a result of incident light having a light intensity of I 0 (») at a wavelength » (nm) having passed through a resin film in a thickness direction of the resin film, the resin film being formed from the resin composition and having a thickness of t (µm), is defined as I (»); and
an intensity of transmitted light that is obtained as a result of the incident light having passed through a reference resin film in a thickness direction of the reference resin film, the reference resin film being formed from a reference resin composition obtained by excluding the fluorescent substance and the resin particles from the resin composition, and having a thickness of t ref (µm), is defined as I ref (»).
