[Problem] To provide an artery visualization device capable of very appropriately visualizing a to-be-punctured artery and an artery imaging device used for the artery visualization device. [Solution] An artery visualization device (10) includes an irradiation unit (30) which irradiates the near-infrared light emitted from a light source (32) toward a back-side skin surface (22) at a visualization site (20) where a to-be-punctured artery (21) is running, a light guiding part (40) which encapsulates the light source and is pressed against the back-side skin surface and which is formed with a material of transmitting the near-infrared light emitted from the light source and suppressing reflection of the near-infrared light on the surface of the back-side skin surface, an optical filter (50) which blocks visible light and transmits the near-infrared light passing through a front-side skin surface (23) at the visualization site, a camera (60) (an imaging unit) which receives the near-infrared light passing through the optical filter to capture an image of the visualization site (20), and a monitor (70) (a display unit) which displays the image captured by the camera.
