An electrode plate for a battery is constructed from a porous metal body having at least one low-porosity part selectively arranged therein. A porous resin core is coated with a paste having a metal component, passed through rolls provided with at least one recess to thereby form at least one low-porosity part and sintered. The resultant electrode plate for battery is not only ensured with respect to strength and capable of improving battery performance but also advantageous in that it is available at lowered cost and free from apprehension of supply of raw materials.

The present invention provides a car exhaust purifying filter member which is high in the capacity to collect solid and liquid contents in exhausts and which has such high heat resistance as to be capable of withstanding heat when burned for cleaning and a method of manufacturing the same. A three-dimensional mesh-like metallic porous member made from Ni--Cr--Al and having a three-dimensional framework is heated at 800-1000 .degree. C. in the atmosphere to form on its surface a densely grown fibrous alumina crystal. This member is used as a filter member. Such a filter member shows excellent collecting capacity and corrosion resistance and can withstand high temperatures. Also, it is possible to firmly carry a catalyst on the fibrous alumina crystal formed on the surface. Because of its increased surface area, it has an increased catalyst carrying capacity.

In combination with a diesel engine, a particulate trap for purifying the diesel exhaust of the engine includes a case provided in the exhaust line of the diesel engine and a filter element mounted in the case. The filter element is a porous member of a heat-resistant metal framework having the form of a three-dimensional mesh. The surface roughness of the metal framework is at least 0.2 .mu.m. The pores of the porous member have an average diameter of 0.1-1 mm, the average number of such pores as counted in the thickness direction of the porous member is 10 or more, the volume packing density of the filter element to the entire filtering space is 10-40%, and the filter has a gas inflow filtration area of 400 cm.sup.2 per liter of the displacement of the engine to which the trap is to be mounted. The filter element has a high capacity to collect particulates and can withstand thermal shock during regeneration and yet produces little pressure drop in the exhaust line during filtration.
