An arterial visualization apparatus 1 for irradiating near-infrared light to the skin on the dorsal side of the wrist to form a near infrared image of the wrist comprises a placing table 20 on which a wrist is placed, an irradiating section 3 including a light source 2 emitting near-infrared light, An imaging section 10 that receives light emitted from the skin on the dorsal side of the wrist and that is emitted from the skin on the front side and forms a near infrared image of the wrist, an optical filter 12, and a monitor 14. The arterial visualization device 1 has a convex portion 4 protruding from the wrist placement surface 21 a of the placing table 20 and compresses the skin on the dorsal side of the wrist placed on the placing table 20 from the back side of the wrist And emits the near-infrared light emitted from the light source 2 to the dorsal skin. The placing table 20 has a central placing part 21 and a hand back contact part 23, the hand back contact surface 23 a obliquely intersects with the wrist placing surface 21 a, and the hand rest back contacting part 23 on the central placing part side And the end 23 q of the hand back contact portion on the opposite side with respect to the end portion 23 p is located below. According to the arterial visualization apparatus 1, it is possible to obtain a clear artery image by compressing the skin with an appropriate pressure with a simple configuration.手首の背側の皮膚に近赤外光を照射して手首の近赤外線画像を形成する動脈可視化装置1が、手首を載せる載置台20、近赤外光を発する光源2を含む照射部3、手首の背側の皮膚から入射し、表側の皮膚から出射した光を受光し、手首の近赤外線画像を形成する撮像部10、光学フィルタ12、及びモニター14を備える。動脈可視化装置1は、載置台20の手首載置面21aから突出した凸部4を有し、該凸部4は手首の背側から載置台20に載せた手首の背側の皮膚を圧迫すると共に、光源2が発した近赤外光を背側の皮膚に出射する。載置台20は、中央載置部21と手背当接部23を有し、手首載置面21aに対して手背当接面23aが斜交し、手背当接部23の中央載置部側の端部23pに対して、それと反対側の手背当接部の端部23qが下方にある。この動脈可視化装置1によれば、簡便な構成で皮膚を適切な圧力で圧迫し、鮮明な動脈画像を得ることができる。
