A knock sensor adapted to detect high-frequency knocking, which can be easily manufactured. A signal processor (10) and a sensor element (11), composed of a semiconductor and weighing less than one gram, are mounted on a fixed pedestal (9) which is fixed to a connector (2) with a bonding agent, etc. The connector (2) is fixed to a housing (1) by caulking (16). As a result, the sensor element (11) is set in the space formed by the pedestal (9) and housing (1). <IMAGE> |
