Abstract

A resistor contains a resistance body and a pair of electrodes (a first electrode body and a second electrode body), wherein end surfaces of the resistance body are respectively abutted to and bonded to end surfaces of the electrodes (a first electrode body and a second electrode body), the electrodes (a first electrode body and a second electrode body) each includes a main body portion and a leg portion, the leg portion protruding from the main body portion in the mounting surface of the resister, and a length dimension of the resistor is equal to or shorter than 3.2 mm.

Claims (13)

1. A resistor comprising a resistance body and a pair of electrodes connected to the resistance body, wherein

end surfaces of the resistance body are respectively abutted to and bonded to end surfaces of the electrodes,

the electrodes each includes a main body portion and a leg portion, the leg portion protruding from the main body portion in a mounting surface of the resistor,

the main body portion and the leg portion are formed integrally with each other,

where T 2 denotes a length of the leg portion and T 1 denotes a length of the resistance body in a thickness direction, T 2 is smaller than T 1 , and

a length dimension of the resistor is equal to or shorter than 3.2 mm.

2. The resistor according to claim 1 , wherein in the mounting surface of the resistor, a boundary portion between the resistance body and the main body portion is flat.

3. The resistor according to claim 1 , wherein the resistance body and the main body portion are bonded by solid phase bonding.

4. The resistor according to claim 1 , wherein the main body portion has a protruded portion protruded towards the resistance body side.

5. The resistor according to claim 4 , wherein a protruded length of the protruded portion is longer than a length of the resistance body.

6. The resistor according to claim 1 , wherein an edge side of the leg portion on a side of the mounting surface in a direction in which the resistance body and the electrodes of the resistor are arranged has a chamfered shape.

7. The resistor according to claim 1 , wherein a direction orthogonal to the direction in which the resistance body and the electrodes of the resistor are arranged as well as to a mounting direction of the resistor is set as a width direction, and

a surface of the resistance body is formed with a stripe-patterned grooved and ridged surface, the stripe pattern extending in the width direction.
