wherein first and second side surfaces of the base material opposing each other are exposed from the first through third terminals; and
a protection layer disposed on a surface of the resistance layer exposed from the first through third terminals,
wherein the resistance layer includes a first resistor part connected to the first and second terminals and forming resistance and a second resistor part connected to the second and third terminals and forming resistance, and
the first resistor part and the second resistor part are formed integrally in a single layer.

2. The multi-terminal electronic component of claim 1 , wherein the first through third terminals are not disposed on the first and second side surfaces of the base material.

3. The multi-terminal electronic component of claim 1 , wherein the first and second side surfaces of the base material are entirely exposed.

4. The multi-terminal electronic component of claim 1 , wherein the first terminal extends to a third side surface of the base material perpendicular with respect to the first and second side surfaces of the base material, and the second terminal extends to a fourth side surface of the base material opposing the third side surface of the base material.

5. The multi-terminal electronic component of claim 1 , wherein the first resistor part and the second resistor part each determine a resistance level of one of the first and second resistor parts by trimming one of the first and second resistor parts based on a resistance level of the other of the first and second resistor parts determined through trimming.

6. A board having a multi-terminal electronic component, the board comprising:
a circuit board on which first through third electrode pads are disposed; and
a multi-terminal electronic component disposed on the circuit board,
wherein the multi-terminal electronic component disposed on the circuit board includes a base material, a resistance layer disposed on a surface of the base material, a first terminal and a second terminal spaced apart from each other while covering portions of the resistance layer, respectively, and a third terminal disposed between the first terminal and the second terminal and covering a portion of the resistance layer,
