PROBLEM TO BE SOLVED: To provide a tree-like wax pattern for the lost wax casting method which can improve the production efficiency of a product by the lost wax casting method without any problems with respect to the strength, operation of the lost wax casting method, and the yield of wax. SOLUTION: In the tree-like wax pattern for the lost wax casting method comprising a trunk-like wax pattern, runner part wax patterns extended from the trunk-like part wax pattern in the radial direction in multiple stages, and product part wax pattern fitted to a tip of the runner part wax patterns, large diameter parts and small diameter parts are formed in the trunk-like part wax pattern in multiple stages, the runner part wax patterns are extended from the large diameter part in the radial form.
