Abstract
A gas flow path includes: a filter configured to selectively transmit a gas; a tubular member which is provided downstream of the filter and in which an opening area at a downstream end is smaller than an opening area at an upstream end; and a negative pressure generating device which is provided in a stage subsequent to the tubular member and which is configured to suck the gas that has passed through the tubular member. This provides a gas flow path and a gas detection system which can concentrate a detection-target gas species in a real-time manner.
