An airtight container manufacturing method includes the steps of exhausting an inside of a container through a through-hole provided in the container, arranging a plate member having, at its periphery, grooves penetrating the plate member in its plate thickness direction, on an outer surface of the exhausted container, so as to close up the through-hole, and providing a sealant on the plate member. In addition, a cover member covers the plate member via the sealant, and the container is sealed by closing the cover member on the plate member. In the sealing step the sealant is deformed and flows from the adjacent grooves to form a continuous shape and fill a space between the cover member and the outer surface of the container and along the periphery of the plate member.

A porous layer composed of porous silicon, and the like is formed by anodization and the like on a substrate acting as a vibration sheet of, for example, a liquid discharging head, and a single crystal thin film is epitaxially grown on the porous layer. A lower electrode, a piezoelectric film, and an upper electrode are laminated on the single crystal thin film, and the piezoelectric film is made to a single crystal or a highly oriented polycrystal by a heat treatment. Stress caused by a difference between the thermal expansion coefficient of the substrate and that of the piezoelectric film can be eased by interposing the porous layer therebetween.

A distributed feedback semiconductor laser of the present invention includes a waveguide with an active layer and a diffraction grating, and a first phase shift region formed in the waveguide. The waveguide extends along a cavity-axial direction and is defined such that propagation of light in two different polarization modes is permitted in the waveguide. The first phase shift region extends along the cavity-axial direction and has a polarization dependency that an effective refractive index for propagation light of the first phase shift region differs from an effective refractive index for propagation light of a region of the waveguide other than the first phase shift region such that a phase shift of a quarter wavelength of the propagation light is created for one of the two polarization modes and a phase shift of a half wavelength of the propagation light is created for the other of the two polarization modes in the first phase shift region.
