There are provided an electric injection molding device capable of increasing the response of a driven unit and a molding method using the device. The electric injection molding device includes a driven unit, a motor for operating the driven unit, and a movement direction conversion unit arranged between the motor and the driven unit so as to convert the rotary movement of the rotation generated by driving the motor, into a rectilinear movement. In the motor, the ratio of the layer length of the magnet of the rotor (56) against the inner diameter of the stator (57) is set to 3 or above. Accordingly, it is possible to sufficiently increase the response of the driven unit.
