PROBLEM TO BE SOLVED: To provide novel microcapsules in which photodecomposition of an agrochemical active component is suppressed.SOLUTION: The microcapsules contain (a) an agrochemical active component, a survival rate of which after irradiation with xenon light of intensity of 0.68 W/mat 340 nm with a cutoff at 290nm for 8 hours is 50% or more, and that for 56 hours is 40% or more and 60% or less and (b) a hydrophobic organic solvent. A weight ratio of the agrochemical active component and the hydrophobic organic solvent is 5:95 to 70:30.
