Abstract
Provided is a resistor including a first electrode, a second electrode, and a resistive element disposed between the first and second electrodes. Each of the first and second electrodes includes a main electrode portion and a narrow electrode portion with a narrower width than that of the main electrode portion. The resistive element is disposed between the two narrow electrode portions.
Claims5
A resistor having a length in a length direction, a width in a width direction perpendicular to the length diction, and a thickness in a thickness direction perpendicular to both the length diction and the width direction, the resistor comprising:
- a first electrode, a second electrode, and a resistive element disposed between the first and second electrodes, the first and second electrodes and the resistive element being in alignment in the length direction, wherein each of the first and second electrodes includes a main electrode portion and a narrow electrode portion arranged in the length diction, so that each of the first and second electrodes has a first lengthwise end in the narrow electrode portion and a second lengthwise end in the main electrode portion, the narrow electrode portion being of a width narrower than that of the main electrode portion, and the resistive element having lengthwise ends in the length diction, the lengthwise ends of the resistive element being in contact, respectively, with the first lengthwise ends of the narrow electrode portions;
- and,
- a pair of voltage terminals standing in the thickness direction, respectively, in the first and second electrodes so that each of the voltage terminals is situated at least partially in the narrow electrode portion.
A method for producing a resistor having a length in a length direction, a width in a width direction perpendicular to the length diction, and a thickness in a thickness direction perpendicular to both the length diction and the width direction, the method comprising:
- preparing an electrode material and a resistive material;
- welding the electrode material and the resistive material together to form a joined base material;
- cutting the joined base material to form the register so that the resister comprises a first electrode, a second electrode, and a resistive element disposed between the first and second electrodes, the first and second electrodes and the resistive element being in alignment in the length direction, wherein each of the first and second electrodes includes a main electrode portion and a narrow electrode portion arranged in the length diction, so that each of the first and second electrodes has a first lengthwise end in the narrow electrode portion and a second lengthwise end in the main electrode portion, the narrow electrode portion being of a width narrower than that of the main electrode portion, and the resistive element having lengthwise ends in the length diction, the lengthwise ends of the resistive element being in contact, respectively, with the first lengthwise ends of the narrow electrode portions;
- and
- forming a pair of voltage terminals so as to stand in the thickness direction, respectively, in the first and second electrodes so that each of the voltage terminals is situated at least partially in the narrow electrode portion.
