Abstract
A manufacturing method of an organic-inorganic composite material includes a flocculation and fusion step to flocculate and fuse composite particles in a liquid medium, the composite particles being formed by inorganic fine particles being coated by coating layers. In one embodiment, an average particle diameter of the inorganic fine particles is 1 nm or larger and 30 nm or smaller.
