    摘要： A spark plug includes a tubular metal shell; an insulator including a locking portion locked onto the metal shell; and a cap disposed at a front end side of the metal shell, the cap having a plurality of orifices. The plurality of orifices include orifices with different cross-sectional areas. A sum of the number of one or more largest orifices and the number of one or more large orifices that have a cross-sectional area of larger than or equal to 90% of the one or more largest orifices is smaller than the number of orifices that are other than the one or more largest orifices and the one or more large orifices. A length of the front end portion in an axial direction between a front end of the insulator and a front end of the locking portion is smaller than or equal to 12 mm.

    摘要： A combustion pressure sensor (1) includes a housing (2) having an axial hole (23), a flexible member (8) fixed at one end to the housing (2) and being displaceable along the direction of axis (CL1), a pressure transmission body (3) whose outer circumferential surface is fixed to the other end of the flexible member (8), and a sensor element (42) fixed to the housing (2) and outputting a signal on the basis of a pressure applied thereto from the pressure transmission body (3). The housing (2) includes a main body portion (21) having a screw portion (24), and a cap member (22) having a press contact portion (26) which is pressed against the internal combustion engine when the screw portion (24) is screwed into the mounting hole of an internal combustion engine. The one end of the flexible member (8) is fixed to the main body portion (21).
