    摘要: There is provided a test method for detecting the presence or absence of a defect in a spark plug insulator, including a reference voltage determination process, a test area determination process, a test voltage determination process and a current detection process. In the reference voltage determination process, a reference voltage V F is determined. In the test area and voltage determined processes, test area and voltage are determined so as not to incur a flashover on the basis of a reference insulator of the same material, shape and size as the spark plug insulator when the reference insulator is placed in position between first and second test electrodes. In the current detection step, the test voltage is applied between the first and second test electrodes to detect an electric current between the first and second test electrodes.

    摘要: An ignition plug (1) includes an insulator (2) having an axial hole (4) extending therethrough in the direction of an axial line (CL1), a center electrode (5) inserted into a forward end portion of the axial hole (4), and a metallic shell (3) disposed externally of the insulator (2). The insulator (2) includes a step portion (14) engaged with an inner circumferential portion of the metallic shell (3) and a leg portion (13) extending forward from the forward end of the step portion (14). The porosity of the leg portion (13) is 3.0% or less. Of three regions of the leg portion (13) obtained by radially trisecting it in a cross section perpendicular to the axial line (CL1), the outermost region is defined as a first region (AR1) and the innermost region is defined as a second region (AR2). The porosity of the first region (AR1) is equal to or more than 1.20 times the porosity of the second region (AR2).
