  "textContent": "[Problem] The present invention has been made in view of the above problem; it is an object of the present invention to simplify, in an electrically controlled construction machine, a wiring of a wire harness between a controller and a control valve.[Solution] On a turn frame 7 of an excavation machine, a hydraulic oil tank 48 is placed in the center of a right engine chamber 9a in the front-back direction, a control valve is placed in front of the hydraulic oil tank, a battery 49 is further placed in front of the control valve 45, and a cool mechanism 60 is placed behind the hydraulic oil tank 48. The control valve 45 is supported by a support member 52, and a controller 51 that outputs a signal for driving the control valve 45 is mounted to a side plate part 52c of the support member 52, thereby to be placed in a position in front of the control valve 45 and above the battery 49.",
