PROBLEM TO BE SOLVED: To provide an alternator for a vehicle which can secure a high space factor and a cooling performance so as to achieve high-output with a small size, and is inexpensive. SOLUTION: This alternator is provided with a rotor iron cores 71 and 72, having 2p magnetic poles and armature winding 31 constituting m phases of winding, and the number of slots of armature iron core 32 is 2 pmn (>=2), and the number of conductors inserted into one slot is 2, and two conductors are arranged in one row in the radial direction within the slot, and the sections where the inner conductor within the k-th slot and the outer conductor within the (k±mn)-th slot are connected with each other, being twisted in the radial direction in an optional position between the kth slot and the (k±mn)-th slot at the coil end are provided by 2n(2p-1) places per phase, and the conductors stored in n pieces of plural adjacent slots are connected with one another, and one phases of the coils is made.
