the first solid electrolyte material is represented by chemical formula (1) below:
LiαMβOγXδ  (1)
where α, β, γ, and δ are all greater than 0,
M is at least one element selected from the group consisting of metal elements other than Li, and metalloids,
X is at least one element selected from the group consisting of Cl, Br, and I, and
