    Abstract: The present invention provides a microcapsule encompassing water or a water-soluble compound and having excellent leakage resistance and morphological stability. Further, the present invention provides a method for producing the microcapsule.
    The microcapsule of the present invention is a microcapsule encompassing at least one of water or a water-soluble compound, in which a capsule wall of the microcapsule contains a resin having a repeating unit derived from a hydrophobic monomer having a ClogP value of 0.70 or more and a repeating unit derived from a hydrophilic monomer having a ClogP value of less than 0.70, and the microcapsule satisfies a relationship of Expression (1). δ / Dm ≤ 0 . 4 ⁢ 0 Expression ⁢ ( 1 ) δ represents a number average wall thickness (μm) of the microcapsule. Dm represents a volume-based median diameter (μm) of the microcapsule.
