Abstract
Disclosed is an ultra-low temperature freezer comprising a seal. The seal member has: hollow first and second air layer forming portions which are aligned in a row in a second direction between a first and second peripheral edges when a door is closed; and a first connection portion which is connected between the first and second air layer forming portions so as to form an air layer. The first connection portion has a shape that would overlap part of the first and second air layer forming portions if moved in parallel to the second direction. The outer peripheral surface of the first connection portion and the outer peripheral surfaces of the first and second air layer forming portions form first and second recessed portions extending in a first direction.
