PROBLEM TO BE SOLVED: To provide an injection molding machine capable of improving the cost and performance of members forming an electromagnet.SOLUTION: The injection molding machine 10 includes: a first fixed member 11 for mounting a fixed mold 15; a first movable member 12 for mounting a movable mold 16; a second movable member 22 moving together with the first movable member 12; and a second fixed member 13 arranged between the first movable member 12 and the second movable member 22. A groove 45 is formed in one of the second movable member 22 and the second fixed member 13 for storing a coil 48 of the electromagnet 49. The coil 48 of the electromagnet 49 is formed by regularly winding coil wires 48a. At least the winding number of an n-th layer (n is a natural number not less than 3) which is the outermost layer is smaller than a winding number of the second layer when n is an even number and smaller than a winding number of a first layer when n is an odd number. Thereby a lacking part 52 is formed. |
