A claw pole generator is basically provided with a circularly arranged permanent magnet and an internal stationary unit with a yoke and a coil. The yoke includes a first laminated yoke and a second laminated yoke. The first and second laminated yokes include a disc-shaped connecting portion arranged on one side of the coil and a plurality of outer circumferential yoke portions that are arranged between the coil and the permanent magnet with circumferential spaces in-between. Each of the outer circumferential yoke portions has a plurality of outer circumferential yoke layers laminated overlying each other along a radial direction with respect to the axial centerline of the coil. An outermost one of the outer circumferential yoke layers that is closest to the permanent magnet with a longer axial length than an innermost one of the outer circumferential yoke layers.
