Abstract
Official abstract text for this publication.
Provided is a resistor for current detection, wherein connection failure etc. due to electro-migration is prevented from being generated in state that the resistor is mounted on a mounting board. The resistor has a resistance body ( 11 ) and electrodes ( 12 ). The electrode ( 12 ) includes first electrode portion ( 12 a ) connected to the resistance body ( 11 ) and second electrode portion ( 12 b ) formed on the first electrode portion ( 12 a ). The second electrode portion ( 12 b ) consists of material having higher resistivity than the first electrode portion ( 12 a ) and solder, which is used for mounting the resistor on the mounting board.
First claim
Opening claim text (preview).
The invention claimed is: 1. A resistor having a resistance body and electrodes, comprising: the electrode including first electrode portion connected to the resistance body and second electrode portion formed on the first electrode portion; the second electrode portion consisting of material having higher resistivity than the first electrode portion and having higher resistivity than solder, which is used for mounting the resistor on a mounting board. 2. The resistor according to claim 1 , wherein the electrode further includes third electrode portion, and wherein the second electrode portion intervenes between the first electrode portion and the third electrode portion, and resistivity of the material of the second electrode portion is higher than that of the third electrode portion. 3. A structure for mounting a resistor having a resistance body and electrodes on circuit wiring pattern formed on a mounting board, comprising: the electrode including first electrode portion connected to the resistance body and second electrode portion formed on the first electrode portion; the second electrode portion and solder intervening between the circuit wiring pattern and the first electrode portion; and the second electrode portion consisting of material having higher resistivity than the first electrode portion and the solder used for mounting the resistor on the mounting board.
