ABSTRACT:
A spark plug is provided with a built-in, ring-shaped pressure sensor. The pressure sensor is composed of a plate packing, a piezoelectric element, an electrode plate and an insulating plate stacked one over the other and also includes a lead wire extending from the electrode plate through a through-hole formed in an upper part of a base portion of a metal shell to output electrical signals. The pressure sensor is accommodated in a cylindrical metal casing of L-shaped cross-section and disposed above a gasket and on the base portion. The metal casing is integrally welded over an entire circumference thereof to the base portion at an upper edge and also at a lower edge, whereby the pressure sensor is sealed within the metal casing.
