Disclosed is a coated seed which is obtained by coating a seed with a coating material that contains an inorganic mineral powder having an average particle diameter of 1-100 μm and a thermosetting resin powder having an average particle diameter of 10-200 μm. The coated seed is characterized in that the thermosetting resin powder is obtained by aggregating a powdery agrochemical with a thermosetting resin. Consequently, the coating seed exhibits excellent performance.
