Provided is a slurry capable of producing an electrode layer having high ion conductivity and high strength even when an inorganic solid electrolyte is used. SOLUTION: Active material particles and / or sulfide-based solid electrolyte particles, a binder, and a nitrile solvent, m: n = 50 to 90: 50-10 (where m is the formula (1) in the binder) And n is the total weight% of the repeating unit represented by the formula (2) in the binder.), And 0.1 ≦ 100 × x / y ≦ 20 (wherein , X represents the weight of the binder in the slurry, and y represents the weight of [the weight of the binder in the slurry + the weight of the sulfide-based solid electrolyte particles in the slurry + the weight of the active material particles in the slurry]). The binder has a repeating unit represented by the formula (1) and a repeating unit represented by the formula (2), and the nitrile solvent is a slurry represented by the formula (3). Formula (1)-(— CF 2 CH 2 —) — Formula (2) — (— CF 2 CF (CF 3 ) —) — Formula (3) R—C≡N [Selection figure] None |
