    摘要: An adhesion of a nickel plating layer to a metal shell is improved, and an effect of improving a corrosion resistance by providing the nickel plating layer is sufficiently exerted. A spark plug 1 includes a cylindrical metal shell 3 that extends in an axial CL1 direction, and a nickel plating layer 31 that is made of metal containing nickel as a main component and covers an outer surface of the metal shell. In a monochrome image of 256 gradations where black is 0 and white is 255, which is obtained by observing a cross-section perpendicular to an outer surface of the nickel plating layer by a transmission electron microscope with an acceleration voltage of 200 kV, an average value in 256 gradations of the monochrome image is 170 or larger and 230 or smaller.

    摘要: A spark plug superior in salt corrosion resistance and stress corrosion cracking resistance is provided. The park plug includes a metallic shell coated with a composite layer which includes a nickel plating layer and a chromate layer formed on the nickel plating layer. The spark plug is characterized in that the nickel plating layer has a thickness A which satisfies a relational expression 3 μm≦A≦15 μm and that the chromate layer has a thickness B which satisfies a relational expression 2 nm≦B≦45 nm.

    摘要: A malfunction determining unit 7 compares an absolute value of the difference between a first count and a second count stored in a storage unit 8 with a predetermined threshold. If the absolute value is less than a predetermined upper limit, the malfunction determining unit determines that a contact unit 1 has no malfunction. If the absolute value is the upper limit or more, the malfunction determining unit 7 determines that the contact unit 1 has malfunction, and supplies the determination result to a control unit 3. The control unit 3 allows an output unit 10 to output a malfunction detecting signal if receiving the determination result indicating the presence of malfunction from the malfunction determining unit 7.

    摘要: A contact resistance value detected by a detection means (a resistance detection part) is compared with a predetermined threshold value. A determining means (an abnormality determining part) determines that there is a failure when the contact resistance value exceeds the predetermined threshold value, and then an abnormality detection signal is outputted from an output means (an output part). Therefore, it is possible to detect a failure in a contact, such as oxidization generated on a surface of a contact or contact pressure reduction generated between contacts, based on the contact resistance value of a contact part.
