The present invention aims to maximize the advantageous physical properties of sulfur and provide a cathode mixture that can be suitably used in a cathode mixture layer of an all-solid-state lithium-sulfur battery having excellent charge/discharge capacity. The present invention also aims to provide an all-solid-state lithium-sulfur battery including a cathode mixture layer containing the cathode mixture. The present invention relates to a cathode mixture for use in a cathode mixture layer of an all-solid-state lithium-sulfur battery, the cathode mixture containing the following components (A) to (D) : (A) sulfur and/or its discharge product; (B) elemental phosphorus and/or P x S y where x and y independently represent an integer that gives a stoichiometric ratio; (C) an ion-conductive material; and (D) a conductive material.
