The first and second slits have first and second facing portions facing each other. The first facing portion has a first inner end and a first outer end. The second facing portion has a second inner end and a second outer end. An inter-slit portion is provided between the first and second facing portions and is defined by a first straight line connecting the first and second inner ends and a second straight line connecting the first and second outer ends. In a radial direction of the rotor core, a minimum distance D1 from the inner circumference to the slits, a minimum width W1 of the slits, and a length W2 of the inter-slit portion satisfy at least one of D1
