Abstract
An object of the present invention is to suppress variations in shape of flow channels to have an enlarged flow channel. When an attachment main bodyof a lid memberis attached to a recessed attachment partof a main body member, a pair of flange partsprovided to the lid memberabuts on the main body member. Therefore, the insertion amount of the attachment main bodyinto the recessed attachment partin each product can be maintained approximately constant while enlarging a main channel MC and a pair of sub channels SSand SS, which are formed by the main body memberand the lid member, and variations in shape of these flow channels can be reliably suppress. The contact surfaces between the lid memberand the main body membercan be bent by providing the flange parts, and when forming a covering member, the molten resin can be prevented from leaking from the outside of the lid membertoward the main flow channel MS and the pair of sub flow channels SSand SS, and as a result, variations in shape of the flow channels can be reliably suppressed.
