Abstract
A method for manufacturing a zinc ferrite film includes forming a zinc ferrite film on a base material by having a reaction liquid, which contains metal ions including only bivalent iron ions and bivalent zinc ions, contact an oxidation liquid, which contains an oxidant that oxidizes the metal ions, in the presence of a pH adjuster. The pH adjuster includes a carbonate of ammonium and an alkali metal salt of mono-carboxylic acid.
