Abstract
A chip having a deaerating function and requiring no bonding or welding for forming a channel, and an apparatus and method for the reaction analysis are provided. The chip contains a first substrate, a second substrate having a liquid inlet and a liquid outlet, and an intermediate member having hydro-phobicity and air permeability and forming a channel between the first and second substrates. It is thereby possible to prevent mixing of air bubbles into the channel.
