Electronic control unit and vehicle behavior control device

A vehicle behavior control device comprising a base body having a brake fluid path formed therein, and an electronic control unit the electric control unit comprising:

• a sensor board to which a sensor for detecting a predetermined physical quantity is attached, wherein the sensor comprises an angular velocity sensor and an acceleration sensor;
• a control board which controls a brake fluid pressure in the brake fluid path by controlling an operation of an electric part based on a behavior of a vehicle body detected by the sensor;
• and
• a housing which accommodates the sensor board and the control board,
• wherein the housing has a first room for accommodating the electric part, a second room for accommodating the sensor board and the control board in a stacked condition, and a partition portion for separating the first room and the second room from each other,
• wherein a recess which is opened to the second room is formed in the partition portion, and a sensor accommodating portion for accommodating the sensor is formed using the recess,
• wherein the sensor accommodating portion is enclosed by the sensor board directly contacting the partition portion,
• wherein the control board directly contacts the partition portion, and
• wherein the sensor board is mounted on a face of the partition portion at the second room side.
