An electronic apparatus that allows data to be written efficiently to an EEPROM with provisions made to greatly reduce the risk of the data stored in the EEPROM being altered in the field, and a production method for the same are achieved. The method is the production method for the electronic apparatus which comprises a board having a separable region and mounted with a central processing unit, an electrically alterable nonvolatile storage device, and a connector mounted on the separable region, and is configured so that when the region is separated, data cannot be written to the storage device by directly controlling an internal circuit of the central processing unit, and the production method for the electronic apparatus comprises: a writing step of writing data to the storage device by connecting an external apparatus to the connector and by directly controlling an internal logic circuit of the central processing unit; and a separating step of separating the region after the writing step.
