  "textContent": "Provided is a phosphor having a favorable emission peak wavelength, a narrow spectrum halfvalue width, and a high emission intensity. Furthermore, provided are a light emitting device, an illumination device, an image display device, and a vehicular display lamp having favorable color rendering or color reproducibility, and favorable conversion efficiency. The present invention relates to: a phosphor containing a crystalline phase having a composition represented by a specific formula, wherein when the peak intensity appearing in the 2θ=38-39 degrees region in an X-ray powder diffraction spectrum is defined as Ix, and the peak intensity appearing in the 2θ=37-38 degrees region is defined as ly, Ix/ly which is the relative intensity of Ix relative to ly is 0.140 or lower; and a light emitting device comprising said phosphor.",
