Liquid discharge head and recording apparatus
Abstract:
A liquid discharge head includes a flow channel member including a first surface and a second surface opposite to the first surface, and a pressing unit on the first surface. The flow channel member includes a first discharge hole and a second discharge hole in the second surface, a first individual flow channel connected to the first discharge hole, a first pressurizing chamber on an upstream side of the first discharge hole in the first individual flow channel, a second individual flow channel connected to the second discharge hole, a second pressurizing chamber on an upstream side of the second discharge hole in the second individual flow channel, and a manifold commonly connected to an upstream side of first individual flow channel and an upstream side of the second individual flow channel. The first individual flow channel and the second individual flow channel have an overlapping portion in plan view.
