PROBLEM TO BE SOLVED: To provide a molten metal feeding apparatus in die casting capable of securely performing the feed of a lubricant. SOLUTION: Regarding the molten metal feeding apparatus where a molten metal is poured from an injection sleeve 7 into a cavity 6 formed of the boundary faces 4a, 5a of a pair of dies 4, 5, the apparatus is provided with: a lubricant feeding means 10 of jetting a powdery lubricant and air to a sliding face at which a piton 7b of the injection sleeve 7 is slid; and an automatic spray mechanism 8 having a releasing agent feeding means 9 of feeding a liquid releasing agent to the boundary face. When the releasing agent feeding means jets the releasing agent, the lubricant feeding means jets the air, and prevents the releasing agent from infiltrating into the lubricant agent feeding means.
