PROBLEM TO BE SOLVED: To provide an integrated electric power steering apparatus that has high durability and reliability, and enhances heat dissipation performance of a heat generation element while improving the simplification and assembly of a structure.SOLUTION: An electric motor section 40, a speed reduction mechanism section 20, and a controller section 50 are integrally fixed together. The controller section 50 includes: a heat generating element 531 including at least a control circuit element, and for generating heat by operating; a control board 53 having the heat generating element 531 mounted thereon; and a mechanism member 500 in which the control board 53 is fixed. The controller section is configured such that at least a portion of the heat generated by the heat generating element 531 can be transmitted to the mechanism member 500 via a thermally conductive member 57. |
