Abstract
A manufacturing method of a resistor contains: a step of forming a resistor base material by stacking an electrode material, a resistive material, and an electrode material in this order and by bonding the electrode material, the resistive material, and the electrode material by applying pressure in the stacked direction; a step of passing the resistor base material through a die, the die being formed with an opening portion having a dimension smaller than an outer dimension of the resistor base material; and a step of obtaining an individual resistor from the resistor base material passed through the die.

- a step of forming a resistor base material by stacking an electrode material, a resistive material, and an electrode material in this order and by bonding the electrode material, the resistive material, and the electrode material by applying pressure in a stacked direction;
- a step of passing the resistor base material through a die, the die being formed with an opening portion having a dimension smaller than an outer dimension of the resistor base material;
- and
- a step of obtaining an individual resistor from the resistor base material passed through the die.
A resistor mounted on a circuit board, the resistor comprising:
- a resistive material;
- a first electrode material bonded to a first end surface of the resistive material;
- and
- a second electrode material bonded to a second end surface of the resistive material, wherein
- a surface of the resistor is formed with stripe-patterned grooves and ridges extending in a direction orthogonal to a bonding direction in which the first electrode material, the resistive material, and the second electrode material are arranged side by side.
