A combustion pressure detection device for detecting the combustion pressure in a combustion chamber of an internal combustion engine, characterized in that: the combustion pressure detection device can be mounted to a communication hole (4a) so that an inner portion and an outer portion of a cylinder head (4), which forms the combustion chamber, are in communication; the combustion pressure detection device includes a housing (30), and a piezoelectric element that detects the combustion pressure in the housing (30); the housing (30) includes a mounting structure portion that can be mounted to the communication hole (4a); the mounting structure portion includes a third outer circumferential surface (333) to which a first seal member (71) can be mounted, and an inclined surface (315a) to which a second seal member (72) can be mounted; and when the combustion pressure detection device is mounted to the communication hole (4a), the inclined surface (315a) is disposed further toward the tip end side in the direct
