The electronic control device is provided with a control substrate, a heat-generating electronic component mounted on the control substrate, and a heat sink provided with a heat-dissipating material interposed therebetween with respect to the heat-generating electronic component, the heat sink including at least: a distal-side contact section that comes into contact with the control substrate at a position distal from the heat-generating electronic component, and a distal-side contact section that comes into contact with the control substrate at a position distal from the heat-generating electronic component; and a near-position-side abutting part which abuts against the control substrate at a position away from the heat-generating electronic component and is not fixed to the control substrate at a distance shorter than the distance between the heat-generating electronic component and the far-position-side abutting part. As a result, a decrease in heat dissipation performance can be suppressed.
电子控制装置具备控制基板、安装于该控制基板上的发热电子部件、以及相对于该发热电子部件隔着散热材料设置的散热器,散热器至少包含:远位侧抵接部,其在远离发热电子部件的位置与控制基板抵接;近位侧抵接部,其以比发热电子部件与远位侧抵接部之间的距离短的距离,在远离发热电子部件的位置与控制基板抵接而不固定于控制基板。由此,能够抑制散热性的降低。
