A stator of a rotating electric machine including a rotor and such stator, comprising:

• a stator core having a plurality of slots formed in parallel with a rotational axis of said rotating electric machine;
• and
• a coil plate laminate having a configuration that a plurality of coil plates each having an insulating member attached to at least one side thereof are laminated in a radial direction, wherein
• said coil plate has an “I”-shaped portion to be inserted into said slot, and
• said coil plates opposite to each other are formed such that a shortest distance between end faces of said “I”-shaped portions in a width direction is longer than a shortest distance between end faces of said “I”-shaped portions in the thickness direction.
