A rotating electrical machine is equipped with a stator including a stator winding and a stator core with slots. The stator winding includes phase coils each of which is wound in the slots and connected at an end to a phase terminal and at the other end to a neutral point. The phase coils are each made up of unit coils connected in series between a corresponding one of the phase terminals and the neutral point and connected together using connecting conductors. Each of the phase coils includes two or more reversing connecting conductors each of which orients a direction in which the connecting conductor extends from the (i+1)unit coil to the (i+2)unit coil to be opposite to that in which the connecting conductor extends from the iunit coil to the (i+1)unit coil. This coil layout ensures a desired degree of electrical insulation in the stator.

A sensor device includes a sensor element detecting a temperature of an attachment member to which the sensor device is attached. The sensor device includes a flexible substrate that includes a base having a first surface and a second surface and made of an electrically insulating material, and a land disposed adjacent to the first surface and electrically connected to the sensor element. The sensor device further includes: a rigid member adhered to the second surface; a flexible member that has a thermal conductivity and a flexibility higher than those of the base, is stacked on the rigid member to be in contact with the rigid member on a side opposite to the flexible substrate, and is to be in contact with the attachment member in an attached state; and a pressing member that presses the flexible substrate toward the attachment member in the attached state.
