A method of producing an M-C-N-O based phosphor with reduced non-uniform emission and improved color purity is provided. The method of producing an M-C-N-O based phosphor comprising a group IIIB element (M), carbon (C), nitrogen (N) and oxygen (O) comprises: heating a mixture comprising a group IIIB element-containing compound and a nitrogen-containing organic compound to form a pyrolysate; disintegrating the resulting pyrolysate-containing product; and firing the disintegrated product.

The present invention relates to an electronic device having an electronic device body 1 the surface of which is covered by a protective sheet. The protective sheet includes a multilayer structure including a base (X) and a layer (Y) stacked on the base (X). The layer (Y) includes a metal oxide (A), a phosphorus compound (B), and cations (Z) with an ionic charge (Fz) of 1 or more and 3 or less. The phosphorus compound (B) includes a compound containing a moiety capable of reacting with the metal oxide (A). In the layer (Y), the number of moles (N M ) of metal atoms (M) constituting the metal oxide (A) and the number of moles (N P ) of phosphorus atoms derived from the phosphorus compound (B) satisfy a relationship of 0.8 ≤ N M /N P ≤ 4.5, and N M , the number of moles (Nz) of the cations (Z), and Fz satisfy a relationship of 0.001 ≤ Fz × N Z /N M ≤ 0.60.
