发明名称 Resistor and method of manufacturing the same
摘要 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 (21), a pair of first upper surface electrode layers (22), each provided on a side portion of an upper surface toward a portion of a side surface of the substrate (21), a pair of second upper surface electrode layers (23) provided in a manner to make electrical connections with the first upper surface electrode layers (22), a resistance layer (24) provided in a manner to make electrical connections with the second surface electrode layers (23), and a protective layer (25) provided to cover at least an upper surface of the resistance layer (24). 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 (22) on side portions of an upper surface toward portions of side surfaces of the substrate (21), thereby attaining a reduction of the actual mount area on the mount board, including soldering portions.
