Production subject matter utilized in the learning area of "energy conversion technology" in technology education course in junior high schools in Japan was developed. Developed production subject matter is a robot, which runs on a hula-hoop with a motor, and an electric double layer capacitor is used as its power supply. The structure of the robot is simplified with restricting the number of motors as its power source to only one, therefore the production of the robot can be completed in short class hours. Furthermore, learning about the effective use of energy also become possible through the measurement of charged quantity and discharged quantity of electricity by utilizing the electric double layer capacitor as its power supply. As a result of experimental class performed with the robot as the production subject matter, the robot could be completed in regulated class hours and the students' consciousness about the effective use of energy was promoted.
