To provide a motor control device mounted with a memory element in which a program for motor control is appropriately written by on-board.
A motor control device 1 of the present invention includes: a circuit board 10 with a memory 13 disposed, in which a control program 15 for driving a motor 2 is to be written; lands 18 that are formed on the circuit board 10 and in which contact probes 34 outputting electrical signals for writing the control program 15 to the memory 13 are to be contacted; and a conductive pattern 19 that transmits the electrical signals outputted from the contact probes 34 from the lands 18 to the memory 13. The lands 18 have through holes 18a, and contact the contact probes 34 by engaging the contact probes 34 to the through holes 18a.
