To provide a device for producing a powder of a coffee raw material, capable of reducing production cost, while securing raw material powder measuring precision, in a case of producing a prescribed quantity of a raw material powder by crushing coffee beans.

This device for producing a powder of a coffee raw material is provided with a controller 10. As sale action executing conditions are met (step 1: YES), the controller 10 starts a coffee mill (step 10), reads an integrated current value SUMI computed by a current value integrating circuit 8 (step 5), and determines an integrated rotation number SUMN by integrating the rotation number N of a mill motor 3b of the coffee mill 3 after starting based on input signals from a rotary encoder 7 (step 6), and stops the coffee mill 3 when SUMN2≤SUMN<SUMN1&SUMI≥SUMI2, or SUMN<SUMN2&SUMI≥SUMI1 is met (steps 8-12).
