BRAKE HYDRAULIC PRESSURE CONTROL SYSTEM AND STRADDLE-TYPE VEHICLE

To achieve a brake hydraulic pressure control system which makes it possible to suppress an increase of the manufacturing cost as compared to existing brake hydraulic pressure control systems which ground a control board using a coil spring. A brake hydraulic pressure control system according to the present invention includes: a metallic substrate () in which a flow channel for brake fluid is formed; and a control board () of a hydraulic pressure control mechanism for the brake fluid provided in the flow channel. The brake hydraulic pressure control system according to the present invention further includes at least one conductive plate spring () which is provided between the control board () and a component that is electrically connected to the substrate (). The free length of the plate spring () is longer than the distance between the control board () and the component, and the plate spring () has a first end part () connected to the control board () and a second end part () connected to the component.
