Abstract: A monitoring device includes an emitting part that emits an ultrasonic wave, a reception part that receives a reflected wave, and a detection part. When the emitting part emits the ultrasonic wave to a bottom of bladder of a subject, the reception part receives a reflected wave from the bottom of bladder, the reflected wave being based on the ultrasonic wave from the emitting part. The detection part detects, based on a result of reception by the reception part, a predetermined movement of the bottom of bladder or an index indicating a moving state of the bottom of bladder.

Abstract: To provide a new aluminium/zinc composite material that is a solid and safe and can be used as a substitute for conventional aluminium pastes or flakes in terms of at least appearance properties. The composite material contains aluminium particles and zinc particles held on the surfaces thereof. The inclusion of such composite particles renders the composite material effectively usable as a substitute for aluminium pastes.
