Abstract: A synthetic resin container and method for manufacturing the same, including a container main body molded into a predetermined container shape and a covering layer laminated on an outer peripheral surface side of the container main body. The method includes heating the composite preform to bring the covering material layer into a molten state or a semi-molten state while softening the preform main body to be stretchable, subsequently molding the composite preform into a predetermined container shape by using a blow molding die in which an edge portion formed by providing a step on a cavity inner peripheral surface extends along a predetermined direction, and providing, in the covering material layer to be molded integrally with the preform main body, a thin portion molded by being brought into pressure contact with the edge portion.

Abstract: A liquid discharge head includes a first substrate in which a nozzle is formed, a second substrate disposed above the first substrate, an energy generation element that generates energy for discharging a liquid by a drive signal being applied, and a vibration plate that vibrates by the energy generated by the energy generation element and that is stacked on the second substrate, in which the vibration plate has a first area and a second area positioned at a position different from the first area and having a lower elastic modulus than an elastic modulus of the first area.

Abstract: A method for manufacturing a container (100) having a covering layer includes: acquiring a preform (200) having a preform covering layer (204) formed by using a synthetic resin having thermoplasticity, the preform being a material for forming a container (100) having a covering layer (104) manufactured by blow molding; setting the preform (200) in a blow mold (310) wherein a blade (440) is provided to a portion of a surface of the blow mold (310) with where the container is brought into contact, the blade having a height that corresponds to a thickness of the covering layer (104); and forming the container (100) having the covering layer (104) by performing blow molding on the preform (200), the covering layer having a slit (190) formed by the blade (440).
