Abstract: Provided is a seal material having high rigidity without deformation or breakage, excellent corrosion resistance to fluid, and low solubility when used under high sealing force, and to provide a flow cell, a detector, and an analyzer in which there is no fluid leakage, contamination of the seal material components is prevented, and the replacement frequency is low. Provided are a seal material for an analyzer, including a resin and at least one layer of fiber sheet embedded in the resin, wherein the at least one layer of fiber sheet is embedded between and in substantially parallel to two seal surfaces: a first seal surface, which is one resin surface of the seal material; and a second seal surface, which is the other resin surface substantially parallel to the former one, and a flow cell, a detector, and an analyzer using the seal material.

Abstract: Provided is a copper fiber nonwoven fabric having a bonding portion between copper fibers, and in the relationship between compressive stress and strain, is provided with a first region exhibiting plastic deformation and a second region exhibiting elastic deformation in which compressive stress is higher than the first region. Alternatively, the copper fiber nonwoven fabric has a bonding portion between copper fibers, and in the relationship between compressive stress and strain, has a region exhibiting elastic deformation, wherein the region exhibiting elastic deformation has an elastic deformation region before an inflection portion a, the inflection portion a, and an elastic deformation region after the inflection portion a.
