A carbon monoxide sensor having a fast response performance without leakage of object gas to an exterior atmosphere is presented. The sensor includes: a proton conductive electrolyte film; two electrodes having catalysts and being disposed at opposite sides of the proton conductive electrolyte film; a positive electrode current collector plate, where a gas passage having a gas inlet and outlet is formed, with the gas passage contacting one of electrodes; a negative electrode current collector plate having plural holes contacting the other of the electrodes; a direct-current power source having positive and negative terminals connected to the positive and negative electrode current collector plates, respectively; and a current detecting unit for detecting a current that varies depending on a concentration of carbon monoxide in an object gas, containing hydrogen, flowing in the gas passage.

A polyamide resin composition comprising a copolyamide and silicate layers originating from a swellable fluoromica, dispersed in said copolyamide on a molecular level, wherein an average thickness and an average aspect ratio (length/thickness) of the silicate layers are within specific ranges. Also disclosed is a process for preparing the polyamide resin composition.

A chip-type solid electrolytic capacitor includes a cathode conductive layer provided on a whole surface of a cathode layer formed on an outer surface of a capacitor element, which whole surface is opposite to a surface where an anode lead wire is lead out, and on a surface adjacent to the first-mentioned whole surface. With this arrangement, if the capacitor element is obliquely inserted into a mold during the formation of a resin shell, the inner walls of the mold will not come into contact with cathode layer of the capacitor element, but will instead come into contact with the cathode conductive layer to prevent the cathode layer from being exposed to the resin shell. As a result, any possible damage to the cathode layer of the capacitor element when the peripheral surface of the resin shell on a cathode side is subjected to roughening is prevented to eliminate defects in electric characteristics such as leakage of electric current and a tan.delta. value.
