PROBLEM TO BE SOLVED: To reduce the cost of a brush holder or a molding device by simplifying the molding device of brush holder for forming the holder body and the connector portion integrally by resin molding thereby performing multiple molding of brush holder. SOLUTION: In the molding device 61 performing injection molding of a brush holder 31 by means of first and second dies 62 and 63 moving relatively in the direction corresponding to the axial direction of an armature shaft, a third die 66 moving in the direction intersecting the direction of relative movement of the dies 62 and 63 perpendicularly is provided, and a hollow connector portion 41 is formed by the third die 66. The first die 62 is provided with a core piece 67 projecting in the direction corresponding to the axial direction of the armature shaft, and a latching groove 47 and a through hole 49 continuous thereto are formed by the core piece 67 in the inner surface 48 parallel with the armature shaft of the connector portion 41.
