PROBLEM TO BE SOLVED: To provide a mold for continuous casting capable of achieving improvement of tenacity and achieving further improvement of thermal shock resistance so as to prolong the life of the mold, and also to provide a method for manufacturing the same. SOLUTION: In the mold for continuous casting and the method for manufacturing the same, a base plating layer 12 and a sprayed coating 13 on which surface roughening process are carried out are sequentially formed at a molten steel contact surface side. The sprayed coating 13 is formed by mixing a granular cermet material A composed of≥10 mass% and≤30 mass% of Cr<SB>3</SB>C<SB>2</SB>,≥5 mass% and≤15 mass% of Ni, and the balance WC with a granular material B composed of Ni or Ni based alloy. A thermal spray particle, in which the material B occupies≥5 mass% and≤30 mass% of a whole, is thermally sprayed by a flame spray machine 14, and the material B is made to exist at the grain boundary of the cermet material A.
