All electric motor unit includes an electric motor and a connection module. The electric motor includes motor coils, a stator and a rotor. The electrical connection module includes a power feed bus bar and a neutral bus bar. The power feed bus bar includes power feed collars for each phase, in which terminal portions for each phase are arranged. The neutral bus bar includes a neutral collar in which neutral terminal portions are arranged. When viewed in a direction intersecting with a second cross section, which intersects with a first cross section containing all the neutral terminal portions, the minimum distance between a second cross-section neutral terminal row on the second cross section and a second cross-section power feed terminal row on the second cross section is greater than zero.
