PROBLEM TO BE SOLVED: To provide a nanoparticle having a function as a host molecule and capable of improving dispersibility and surface orientation of a guest molecule, and to provide a nanoparticle composite obtained by making the guest molecule to be included therein. SOLUTION: The nanoparticle comprises a linear oligomer part having a hydrophilic group and fluoroalkyl groups at both terminals, a three-dimensional silica network part and an organic chain having fluorine or silicon. The nanoparticle has a structure represented by formula (1) äwherein, R's are each independently H or an alkyl group; Xs are hydrophilic groups and each independently an OH group, an NCO group, an NH<SB>2</SB>group or the like; R<SB>F</SB>is a 2-10C fluoroalkyl group having 119-1,000 molecular weight; 3D-SN is a three-dimensional silica network part; Bs are each independently O, O=C-O or the like; E is O, O=C-O, NH-C=O or the like; and G is [(CH<SB>2</SB>O)<SB>l</SB>-[Si(CH<SB>3</SB>)<SB>2</SB>O]<SB>k</SB>-(CH<SB>2</SB>O)<SB>l</SB>] or the like}.
