Abstract: A liquid discharge head includes a first component having a bonding face having a recess and a second component bonded to the bonding face of the first component. The recess includes a first recess to which an adhesive is applied and a second recess extending in an extending direction to connect the first recess and an outer peripheral end of the first component. The first recess includes an inner side face that is an interior of the first component. The second recess includes a first wall face and a second wall face opposed to the first wall face. The first wall face and the second wall face define side walls of the second recess in a width direction orthogonal to the extending direction of the second recess. The extending direction is inclined with respect to a perpendicular line perpendicular to the inner side face of the first recess.

Abstract: The present invention relates to a measurement apparatus capable of improving measurement precision of a measurement object using measurement light without deteriorating the visibility of the measurement object. An observation illumination device 12 has: three types of light sources, i.e., a LED 51 which emits red single-color light, a LED 52 which emits green single-color light, and a LED 53 which emits blue single-color light. The three types of the light of red, green, and blue emitted from the LEDs 51 to 53 irradiates the measurement object 2 at the same time or in a short period of time, thereby becoming observation light, which is perceived by humans as illumination of white light, and irradiates the measurement object 2. The measurement light source 31 is a light source which emits measurement light used in measurement of the shape of the measurement object 2 and is composed of a light source which emits near-infrared single-color laser light having a wavelength different from that of the LED 51. Among the light that enters an optical filter 39 from the measurement object 2, the measurement light transmits therethrough, the observation light is cut off, and the light transmitted through the optical filter 39 forms an image on a light-receiving surface of an image pickup element 41. The present invention can be applied to, for example, a shape measurement apparatus.

Abstract: A liquid discharge head includes a nozzle plate, a channel substrate, a common-liquid-chamber substrate, an adhesive, and a sealant. The nozzle plate includes a plurality of nozzles to discharge liquid. The channel substrate includes a plurality of individual liquid chambers communicated with the plurality of nozzles. The common-liquid-chamber substrate includes a common liquid chamber to supply the liquid to the plurality of individual liquid chambers. The adhesive bonds two of the nozzle plate, the channel substrate, and the common-liquid-chamber substrate. The adhesive faces a channel through which the liquid flows. The sealant surrounds the adhesive at an opposite side of the channel relative to the adhesive.
