Abstract
An ink recorder includes an ink recording section of which ink passage has a small cross-sectional area. For this reason, the ink passage has an opening portion at a bent part thereof which serves as a venting hole for allowing air to be vented from a molding die to the outside therethrough during a molding operation. To prevent ink from leaking from the ink passage, a spherical sealing member is fitted into the opening portion. Since the opening portion is molded of a deformable material, a spherical sealing member made of a metallic material while having a diameter slightly larger than an inner diameter of the opening portion can be fitted into the opening portion.
