Abstract: A physical quantity detection device includes a glass substrate, a substrate including a physical quantity detection part and bonded to a first surface of the glass substrate with a hermetically sealed space being formed inside the substrate, and a function membrane formed on a second surface of the glass substrate opposite to the first surface. The function membrane prevents the second surface of the glass substrate from coming into contact with moisture in the atmosphere.

Abstract: Provided is a connector for connecting an electronic component, which reduces noise radiation when the electronic component is connected to a substrate through the connector and driven. In a connector (100), a connector main body (130) stores a module (210) inside an opening section (110), and the connector main body is mounted on the substrate by being electrically connected to the stored module (210). The connector main body (130) is provided with a contact lead section (120b) which is lead out to the side of the connector main body (130) to be bonded to a conductor on the substrate. A cover member (160) which opens and closes by turning with a shaft section (161) at the center is pivotally supported on the connector main body (130), and the opening section (110) is covered with the cover member (160) from above. The cover member (160) is provided with a conductive skirt section (170) for covering the contact lead section (120b) from above in a closed state.

Abstract: An optical waveguide device includes a lower cladding layer, a high refractive index region provided on the lower cladding layer, a pair of cores provided on the lower cladding layer on both sides of the high refractive index region, and an upper cladding layer provided on the high refractive index region and the pair of cores. One of the upper and lower cladding layers has a pair of band-shaped parts disposed between the high refractive index region and the pair of cores.

Abstract: Scattering loss at a reflecting or transmitting end face of an optical unit is reduced, and the end face is easily manufactured at low cost. An optical waveguide cable (2) as an optical device is provided, as an optical unit, with a core layer (231, 232) serving as an optical waveguide and cladding layers (21, 22) with which the core layer (231, 232) is covered. The core layer (231, 232) and the cladding layers (21, 22) are provided with a diced facet (241) as a processed surface for reflecting light, and a smoothing film (242) is provided on the diced facet (24).
