An optical amplification component 1 includes a heat dissipation plate 10 and an amplification optical fiber 20 arranged on the heat dissipation plate 10. A first fiber portion 20A extending from a reference position RP between a first end E1 and a second end E2 of the amplification optical fiber 20 toward the first end E1 and a second fiber portion 20B extending from the reference position RP toward the second end E2 are wound in a spiral around the reference position RP so as to be along each other as well as not to overlap with each other, and the distance between the first fiber portion 20A and the second fiber portion 20B increases toward the ends thereof. |
