Abstract: A resistor for driving a motor for an air conditioner blower is provided, in which internal resistance bodies are stacked over one after another between insulation plates in the resistor, to accordingly reduce the volume of the entire of the resistor is reduced, and the resistance bodies are separated into a plurality of metal thin plates not a single plate and stacked over one after another, to thereby increase a line width. Also, a temperature fuse is disposed externally. The air conditioner fan blower motor driving resistor is obtained by stacking resistance bodies made of at least two metal thin plates over one after another. The resistance bodies are formed of an independent resistance body forming a second resistance body and a third resistance body on two separate thin plates, and another independent resistance body forming a first resistance body on another thin plate.
