The present invention provides a dispersion composition which is excellent in refractive index and excellent in surface shape after coating, and a curable composition, a transparent film, a microlens, and a solid-state imaging element which are used. The dispersion composition of the present invention includes a metal oxide particle (A) having a primary particle diameter of 1 nm to 100 nm, a polymer compound (B) represented by the following formula (1) having an acid value of less than 120 mgKOH/g, And solvent (C). In the above formula (1), R1 represents a (m+n)-valent linking group, and R2 represents a single bond or a divalent linking group. A1 represents at least one selected from the group consisting of an acid group, a urea group, an urethane group, a group having a coordinating oxygen atom, a group having a basic nitrogen atom, a phenol group, an alkyl group, an aryl group, and an alkylene group. Alkyl group, oxime imido group, alkoxycarbonyl group, alkylaminocarbonyl group, carboxylate group, sulfonylamino group, heterocyclic group, alkoxyalkyl group, epoxy group, isocyanate group and hydroxyl group A monovalent substituent of a group in the group formed. The n A1 and R2 may be the same or different. m is a positive number of 8 or less, n is 1 to 9, and m+n is 3 to 10. P1 represents a polymer chain. m P1s may be the same or different. |
