Provided is a microlens having an inorganic compound layer directly formed on the surface of a base lens material that is resistant to cracking and wrinkling of the inorganic compound layer under high-temperature and high-humidity environment and also to cracking of the base lens material by repeated temperature fluctuation, and an optical device using the microlens. A microlens, comprising a hardened product obtained by polymerization of a polymerizable composition containing a polymerizable monomer and metal oxide fine particles having an average diameter of 1 to 80 nm as essential components and an inorganic compound layer coated on the surface thereof. An optical device equipped with the microlens.
