ABSTRACT:
A sintering method and fusion welding method of the present invention are characterized in that energy is radiated to the black component of starting materials so as to convert it from the state of an energy absorber to the state of an energy reflector (the state where metallic luster is exhibited). The methods can be utilized effectively for forming the electrode of a sensor or the bump of an electronic component. When applied to the production of the sensor and the electrode, the methods can produce these products by a simple production process and with extremely high producibility.
