A plastic formed body having a pouring portfor pouring out highly wetting liquid that wets plastics to a high degree, wherein at least either a surfacethat becomes a liquid-drip flow passage when said liquid drips at the pouring portor a surfacethat becomes a flow passage when said liquid is poured out, is coated with a fluorine-contained resin, and a surface of the fluorine-contained resin coating has an arithmetic mean roughness (Ra) in a range of 0.4 to 200 &#x3bc;m in the surface roughness measurement and an element mean height (Rh) in a range of 0.04 to 10 as defined by mean height (Rc)/element mean length (RSm) in the linear roughness measurement. The formed body effectively prevents said highly wetting liquid from dripping at the pouring port

A stainless steel material for a fuel cell, used for a fuel cell or a cartridge for the fuel cell, having a magnetic permeability of 1.000 to 2.500, and forming a layer having a value of chromium atomic %/iron atomic % of not less than 3.0 in the most surface thereof, and/or the layer of thickness of not less than 12 nm calculated as SiOhaving an oxygen atomic % of not less than 20%. Even when brought into contact with the content solution exhibiting acidity of the fuel cell, the stainless steel material reliably suppresses the elution of metal ions thereof.
