PROBLEM TO BE SOLVED: To provide a method for fabricating bending products which can surely and very quickly eliminate the residual stress of the bending products, dealing with only the targeted spots. SOLUTION: In the manufacturing process of supporters 3 to support the quartz oscillating plate within a quartz oscillator, metal plates 3A that are fixed in a base 2, are pressed into a prescribed shape to become supporters 3 After that, applying a specified amount of voltage between both two ends of the individual supporters 3, causes self-heating by Joule effect at two targeted spots 33, 33 subject to the bending fabrication, which anneals only the needed spots and eliminates the residual stress.
