PROBLEM TO BE SOLVED: To easily and completely deliver stored crystal blanks. SOLUTION: The storing box 10 for crystal blanks includes a storing space 12 having an open top side so that crystal blanks dropped from above the space 12 are received in the space. A groove 32 is formed in a single block material 11 from the upper surface thereof to form the space 12, and an inclined surface 13 is inwardly downwardly formed in the block material 11 to receive crystal blanks. A stainless steel plate is adhered to the surface 13 to form an inner bottom surface 14 of the groove 32 into a concave surface smoothly connected to the surface 13. A side plate 15 is bonded to the left and right portions of the material 11 to form the storing box 10. The groove 32 is surrounded with the side plates 15 to form the storing space 12 having an open top side, and a large number of fine depressions and protrusions are formed on the inside surface 15a of the plate 15 and the surface 14 to prevent crystal blanks from attaching to the surface 15a and surface 14.
