An ophthalmic imaging apparatus that captures a tomographic image of an subject's eye based on light obtained by combining a return light with a reference light, the return light being from the subject's eye when irradiated with a measurement light, the reference light corresponding to the measurement light includes a first optical fiber disposed in an optical path of the reference light and including a light guide portion for guiding the reference light, and a second optical fiber disposed in an optical path of the measurement light and including a light guide portion for guiding the measurement light, wherein a diameter of each of the light guide portions of ejection ends of the first optical fiber and the second optical fiber is larger than a diameter of a light guide portion in a position different from a position of each of the ejection ends.
