摘要：
When examining a living organism exhibiting dynamic behavior such as pulsing, the dynamic behavior is suppressed and clear images are acquired. The invention provides an objective lens unit including a lens barrel for supporting optical components, wherein an end surface of the lens barrel is disposed farther towards the distal side than an optical component at the extreme distal end, and channel-shaped indented portions extending in the diametrical direction are formed in the end surface of the lens barrel.
