PROBLEM TO BE SOLVED: To provide a mold for inexpensively manufacturing a polycrystalline silicon ingot having a good structure of unidirectional solidification, and a method for manufacturing the polycrystalline silicon using the same. SOLUTION: The mold 1 has a bottom section and a side section, and holds and solidifies silicon melt inside the same. When a certain temperature difference is given between the inside surface of the mold 1 and the outside surface of the mold 1, calorific value Qs<SB>1</SB>per unit time/unit area passing through the side section and calorific value Qb<SB>1</SB>per unit time/unit area passing through the bottom section has the relationship of Qs<SB>1</SB><Qb<SB>1</SB>.
