Silica particles comprising:
- silica base particles;
- a reaction product of a trifunctional silane coupling agent, the reaction product covers at least a part of a surface of the silica base particles;
- and
- a nitrogen element-containing compound containing a molybdenum element,
- wherein an amount of the reaction product is 5.5% by mass or more and 30% by mass or less with respect to an amount of the silica particles, and
- a ratio (Mo/Si) of Net intensity of the molybdenum element to Net intensity of a silicon element measured by X-ray fluorescence analysis is 0.035 or more and 0.35 or less.
