PURPOSE: An electric conduction unit manufacturing method which utilizes an environment-friendly material and a speed control method thereof are provided to easily control motor driving speed without manually adjusting a current flowing through an electricity-conducting liquid. CONSTITUTION: An electricity-conducting liquid(1) is inserted into a tube(2). The electricity-conducting liquid includes pure water of 90 percent, salt of less than 7 percent, and pulverized coffee of more than 3 percent. Conductor lines(4,5) respectively penetrate end tube sides(8,9). The conductor line is embedded and attached to the tube. The electricity-conducting liquid inserted inside the tube is separated from the outside which is atmospheric space(10). |
