Abstract
A micro-chemical chip is comprised of a flow passage substrate (110) that includes a substrate (101) of transparent material having a plurality of flow passages (111) in one surface and an optical device (109) built in the other surface as a unit. In a micro-chemical chip manufacturing method according to the present invention, with metal dies 150 and 160 prepared to shape flow passages, wells, and an optical device(s), components such as the optical devices, flow passages, and the like are formed in a single molding process. The present invention is also directed to an optical unit manufacturing method where the atmospheric gas of nitrogen typically employed in the prior art is replaced with any gas of higher heat conductivity such as helium gas to heat and shape material in this alternative atmospheric gas and obtain the molded product.
