In a case where a detector is positioned in a [11-20] direction, and where a first measurement region including a center of a main surface is irradiated with an X ray in a direction within &#xb1;15&#xb0; relative to a [&#x2212;1-120] direction, a ratio of a maximum intensity of a first intensity profile is more than or equal to 1500. In a case where the detector is positioned in a direction parallel to a [&#x2212;1100] direction, and where the first measurement region is irradiated with an X ray in a direction within &#xb1;6&#xb0; relative to a [1-100] direction, a ratio of a maximum intensity of a second intensity profile is more than or equal to 1500. An absolute value of a difference between maximum value and minimum value of energy at which the first intensity profile indicates a maximum value is less than or equal to 0.06 keV.

Silicon carbide single crystal substrate

An ECU () includes a circuit board (), a connector () fixed to the circuit board (), and a resin portion () covering the circuit board () and the connector (). The connector () includes a connector housing () having a terminal holding wall () that separates the internal space from the external space, and terminal fittings () extend through the terminal holding wall (). The connector housing () includes a surrounding wall () disposed on the lateral surface of the terminal holding wall () to surround the terminal fittings (). A potting material () is disposed inside the surrounding wall () and separates the terminal holding wall () from the resin portion (). This can prevent a melted resin from entering a hood () through press fitting holes () at the time of forming the resin portion () by mold forming.
