The electronic device manufacturing apparatus includes a cable holding tool, a work stage, a robot section, a first position detector, a second position detector, and a controller. The first position detector detects positions in a two-dimensional plane direction of the cable held by the cable holding tool and the connector of the electronic device held by the work stage. The second position detector detects positions in a height direction of the cable held by the cable holding tool and the connector of the electronic device held by the work stage. The controller controls the robot section based on the detection result of the first position detector and the second position detector.
