1. A method of manufacturing a motor frame applied to an optical instrument actuator having coils disposed in a magnetic field of a magnet, the method comprising:
(a) inserting a circuit member having a predetermined circuit pattern electrically connected to electronic components and injection molding a resin at a first injection temperature to form a plurality of protective holders;
(b) placing the electronic component on each of the protective holders to form an insert structure;
(c) bending the circuit member to deform the insert structure; and
(d) inserting the insert structure deformed in step (c) and injection molding resin at a second injection temperature to form a frame structure, wherein
the circuit pattern comprises:
a plurality of component connection pattern portions electrically connected to the electronic components, respectively; and
a circuit connection pattern portion configured to connect the plurality of component connection pattern portions to each other, and
step (c) comprises bending the circuit connection pattern portion.
