Abstract
The present invention relates to a resistor and a manufacturing method of the same. The invention aims at providing the resistor and the manufacturing method thereof that can reduce a soldering area that occupies a mount area, when the resistor is mounted on a mount board. In order to achieve the foregoing object, a resistor comprises a substrate ( ), a pair of first upper surface electrode layers ( ), each provided on a side portion of an upper surface toward a portion of a side surface of the substrate ( ), a pair of second upper surface electrode layers ( ) provided in a manner to make electrical connections with the first upper surface electrode layers ( ), a resistance layer ( ) provided in a manner to make electrical connections with the second surface electrode layers ( ), and a protective layer ( ) provided to cover at least an upper surface of the resistance layer ( ). The invention realizes the electrodes on side surfaces of the resistor to have a small surface area because of the pair of first surface electrode layers ( ) on side portions of an upper surface toward portions of side surfaces of the substrate ( ), thereby attaining a reduction of the actual mount area on the mount board, including soldering portions.
