PROBLEM TO BE SOLVED: To provide a robot controller capable of preventing oil sticking around a connector from dripping on an electronic component mounting surface and sticking to an electronic component and also capable of preventing the oil from sticking to the electronic component as much as possible even if an installation method is changed. SOLUTION: When the connector 5 is installed distantly from a floor in the direction of standing a substrate as a countermeasure against oil mist and dust pouring on the floor in a particular environment where the oil mist is suspended in the air, the oil sticking to the electronic component 7 can be reduced by an oil cover 8 covering over the component 7 although the oil sticking around the connector 5 trickles down on the electronic component mounting surface 6a of a printed wiring board 6. In addition, since the oil dripping down into an inner surface of a controller box 2 thinly spreads and stickes, the oil can be prevented as much as possible from dripping from the inner surface and sticking to the electronic component 7 even if the installation method of the robot controller is changed.
