Inorganic filler for low dielectric loss resin composition, slurry composition for low dielectric loss resin composition, low dielectric loss resin composition, molded product for high-frequency equipment, and high-frequency equipment

A slurry composition for a low dielectric loss resin composition in which an inorganic filler is dispersed in a solvent,

• wherein the inorganic filler contains aluminum fluoride having an α phase, and
• a half width of a peak on a (012) plane of an α phase of the aluminum fluoride in an X-ray diffraction pattern is 0.3° or less.

A low dielectric loss resin composition comprising at least a polymer resin and an inorganic filler,

• wherein the inorganic filler contains aluminum fluoride having an α phase, and
• a half width of a peak on a (012) plane of an α phase of the aluminum fluoride in an X-ray diffraction pattern is 0.3° or less.
