Abstract
The present invention is to offer a resistor which can be mounted exactly on the terminals disposed on a circuit board regardless the sides of the resistor, and to offer its manufacturing method by forming the surface of the side-electrode layer at a height higher than the surface of protection layer, or by forming the surface of the second surface electrode layer at a height higher than the surface of protection layer. By these, the resistor can be mounted exactly on the terminal of circuit board at a high yield. Furthermore, since the first surface electrode layer and the second upper electrode layer are electrically connected together through a window provided on the protection layer, a higher connection reliability can be obtained.
