Abstract
A rotary electrical machine for a vehicle according to the present invention is provided with a stator, a rotor which is provided facing the stator and which rotates coaxially with the stator, a power module which is connected to the stator, a capacitor which eliminates or reduces switching noise in the power module and has a pressure release valve, a circuit board on which the capacitor is mounted, and a heat sink which encompasses the capacitor, wherein a semi-closed cell foam seal material is provided in contact with the pressure release valve, and the capacitor is fixed to a terminal fixing section of the circuit board, and is also fixed to an inner side of the heat sink by an anti-vibration bond in a portion different from the terminal fixing section.
