1. A switching element module comprising:
a first switching element and a second switching element connected between a positive electrode and a negative electrode of a direct current power supply;
a smoothing capacitor connected between the positive electrode and the negative electrode of the direct current power supply; and
a cooling block thermally connected to a cooler, wherein
the first switching element is fixed to one side face of the cooling block,
the second switching element is fixed to the other side face of the cooling block that is opposite to the one side face,
the smoothing capacitor is fixed to a positive terminal of the first switching element and a negative terminal of the second switching element, and is provided to face a first connection surface of the cooling block that connects the one side face and the other side face,
the cooling block further has a second connection surface that connects the one side face and the other side face and is opposite to the first connection surface,
the first switching element includes the positive terminal on the first connection surface side and an output terminal on the second connection surface side,
the second switching element includes the negative terminal on the first connection surface side and an output terminal on the second connection surface side, and
the output terminal of the first switching element and the output terminal of the second switching element are connected to each other.
