An inverter apparatus includes a main circuit substrate, an EMC filter substrate, a control substrate, and a panel. The main circuit substrate is configured to convert electric power and includes an output terminal through which the electric power is output from the inverter apparatus. The EMC filter substrate is provided on the main circuit substrate and configured to reduce propagation of electromagnetic noise. The EMC filter substrate includes a first input terminal through which the electric power is input to the inverter apparatus. The control substrate is provided on the EMC filter substrate so that the EMC filter substrate is sandwiched between the main circuit substrate and the control substrate. The control substrate is configured to control the main circuit substrate. The panel is provided on the control substrate so that the control substrate is sandwiched between the EMC filter substrate and the panel.

Inverter apparatus

An electrical machine includes a first substrate, a second substrate, and a conduction support. The first substrate has a mounting surface. The second substrate is disposed in an overlay direction from the first substrate. The conduction support electrically grounds the second substrate and supports the second substrate while keeping approximately no contact with the mounting surface of the first substrate.
