PROBLEM TO BE SOLVED: To provide a glow plug with a combustion pressure sensor capable of carrying out miniaturization and improving durability. SOLUTION: A pressure detecting mechanism 10 is housed in an interior of a housing 1 of the glow plug 100 with a combustion pressure sensor. The pressure detecting mechanism 10 is provided with a pressure detecting element 11. The pressure detecting element 11 is fixed to a tip side of a wiring board 12 arranged in a rear end side than the pressure detecting element 11. A signal conductor 120 for transmitting a signal or the like outputted from the pressure detecting element 11, and an electric power supply conductor 121 for energizing a heater 23 and carrying out heating are formed on the wiring board 12. A pressure transmitting mechanism 20 for transmitting the combustion pressure of the engine to the pressure detecting element 11 is provided in a tip side more than the pressure detecting element 11.
