[Problem] To ensure that a fluid is prevented from overflowing from a well and exposing the user to a biohazard. [Solution] A cartridge for use in measuring a component to be measured contained in a fluid includes a recessed well, formed for storing the fluid, the well including: a lower barrel portion that defines a lower space having a closed bottom; and an upper barrel portion that is formed above the lower barrel portion and defines an upper space having an opening on the top end, wherein a step portion is formed between the lower barrel portion and the upper barrel portion, the step portion being formed on an inner wall surface of the well and defining a step that continuously connects the inner wall surface of the lower barrel portion and the inner wall surface of the upper barrel portion.

To provide a method for manufacturing an optical element, which improves the surface precision of the optical surface as well as reducing the birefringence at a low cost. A method for manufacturing an optical elementA having optical surfacesandand a non-optical surfaceA that is adjacent to the optical surfacevia a ridge by injection molding includes forming the non-optical surfaceA with a mold surface. The mold surface includes a sink forming areaas a first area having a first surface roughness, and a high transfer areaas a second area having a second surface roughness different from the first surface roughness. The second area is located outside the first area.

Optical element and method for manufacturing optical element

An analysis chip contains a test reagent retention member and a sensing member. The test reagent retention member has a housing part for housing the sensing member, and an engaging part for engaging the sensing member within the housing part. The sensing member is secured in the housing part by the engaging part, in such a way as to have a certain area of mobility in relation to the housing part.

A prism used in analysis utilizing surface plasmons is prism of a dielectric medium with a predetermined reflective index. Trapezoidal prism comprises an incident surface on which excitation light is incident from outside, a reflective surface at which the excitation light incident on the incident surface is reflected, an emission surface from which the excitation light reflected by the reflective surface is emitted; and an opposite surface which opposes the reflective surface. The opposite surface is a recessed sink mark surface.
