The optical fiber is positioned in the through-hole from one end to the other end. The through-hole includes a first section, a second section, a third section, a fourth section, and a fifth section. The first section has an inner diameter decreasing farther away from the one end. The second section has an inner peripheral surface contiguous from the first section, and the inner peripheral surface contiguous from the first section extends along the optical axis of the optical fiber. The third section has an inner peripheral surface contiguous from the second section and has an inner diameter decreasing farther away from the second section. The fourth section has an inner peripheral surface contiguous from the third section, and the inner peripheral surface contiguous from the third section extends along the optical axis of the optical fiber.
