Chip resistor, mounting structure for chip resistor, and manufacturing method for chip resistor
Abstract:
A chip resistor includes a first electrode 1, a second electrode 2, a resistor portion 3, a first intermediate layer 4 connected to the first electrode 1 and the resistor portion 3, a second intermediate layer 5 connected to the second electrode 2 and the resistor portion 3, a coating film 61 covering the first electrode 1, and oxides existing in the first intermediate layer 4. The coating film 61 is made of a material having a higher absorptance of a laser beam of a predetermined wavelength than that of the material forming the first electrode 1. The oxides are oxides of the material forming the coating film 61.
