An electronic component includes plural elements, a pair of terminal sections provided to each one of the elements, and a packaging material covering the elements and parts of the terminal sections. A non-conductive shielding section is provided between the terminal sections led outside the packaging material. The presence of the shielding section allows the electronic component to downsize the electronic apparatus, embody a greater density in mounting, and eliminate adverse influence to the apparatus for achieving higher performance as well as improving the durability.

Electronic component

An electronic component is provided which has a plurality of elements, a pair of terminal parts which are disposed on the element, and an armoring material which covers the elements and a part of the terminal parts. The electronic component has a configuration such that the plurality of elements are disposed in the armoring material at a predetermined interval, and a guiding part for guiding the armoring material toward an opposed region of the element is disposed on opposed surfaces between the elements.

An exhaust gas filter having a ceramic filter body is configured such that a specific heat h (cal/g.degree. C.) of ceramic powder constituting the body, and a bulk specific gravity d (g/cm.sup.3) of the filter, satisfy the relation 0.12 (cal/cm.sup.3 .degree. C.).ltoreq.h.times.d.ltoreq.0.19 (cal/cm.sup.3 .degree. C.). The ceramic filter body includes a plurality of cells which extend axially to open at opposite ends of the body. One of the opposite axial ends of each of the cells is closed by a filler in such a manner that the closed ends of the cells and the open ends of the cells are arranged in an alternating configuration. The filter traps particulates in the exhaust gas, and the trapped particulates are removed by regeneration combustion of the filter. The filter exhibits excellent durability, thus preventing the formation of cracks in the surface and interior of the filter. When the filter is mounted on a diesel engine, the diesel engine advantageously does not discharge black smoke.

Exhaust gas filter, method of producing the same, and exhaust gas

An exhaust gas filter for passing exhaust gas of a diesel engine or the like therethrough, thereby removing particulate matter from the exhaust gas. By suitably controlling physical properties of the exhaust gas filter such as a thermal expansion coefficient, the durability of the exhaust gas filter can be enhanced. When a constituent material for the exhaust gas filter includes aluminum titanate as a primary component, the durability can be further enhanced.
