1. A liquid composition, comprising:
a solvent;
an inorganic solid electrolyte; and
a dispersant, wherein
the dispersant is soluble in the solvent, and
a 10% volume fraction-component's particle diameter (D10), a 50% volume fraction-component's particle diameter (D50), a 90% volume fraction-component'particle diameter (D90), and a mode diameter (Dm) of solids contained in the liquid composition satisfy Formulae (1) to (3) below, where D10, D50, D90, and Dm are measured by a laser diffraction method,
D90/D10>10  Formula (1)
D50<1 μm  Formula (2)
Dm<2 μm  Formula (3),
wherein a relative permittivity of the solvent at 25° C. is 6.0 or lower.
