A weight used in a vibration motor includes first and second weight parts that extend along adjacent wing parts to hold the wing parts therebetween; an insertion part that is formed between the first and second weight parts and into which the adjacent wing parts are inserted in the radial direction of the core; and a third weight part that is inserted between the adjacent wing parts (that is, slot) and connects the first weight part and the second weight part in a direction of the rotation axis line such that the insertion part is decoupled. |
