    摘要: To provide a pouring spout in which an open state of the closing member is maintained while contents are being transferred. The above-described problem is solved by a pouring spout (10) including a spout main body (10A) and a closing unit (20). The spout main body (10A) includes at least a bonded part (15), a tubular part (11), and a channel (18). The closing unit (20) includes a closing member (21), an attaching part (24), and a coupling member (23). The spout main body (10A) is formed with an attached part (40). The coupling member (23) couples a first surface of the closing member (21) on the attaching part (24) side and facing the pouch main body part side, and the attaching member (24). The closing member (21) includes a fixed region corresponding to an area of a second surface opposite to the first surface on the attaching part (24) side thereof in which the coupling member (23) is coupled, the fixed region being supported by a nozzle (58) of a packaging container, thereby holding an angle θ formed by the closing member (21) with an end surface of the bonded part (15) on the pouch main body part side at less than 90 degrees.

    摘要: A method for manufacturing a microchip for analyzing a component in a liquid sample by passing the sample through a flow path provided inside and performing a reaction in a reaction portion provided in a portion of the flow path, the method including: a step of providing a substrate including on the surface thereof a groove serving as a flow path and a reaction portion in a portion between the both ends of the groove; a step of applying an adhesive agent or a gluing agent on an area other than the groove on the grooved surface of the substrate; a step of providing a film on an area of which a reaction substance is applied; and a step of attaching the film on the substrate in a specific manner.
