Abstract
There is provided a knocking sensor for an internal combustion engine improved so that electrical damage of a terminal plate in an annular combination member is more certainly prevented. Only two communicating passages separate from each other by substantially 180 degrees are formed in an annular weight of the annular combination member, and resin is filled into an annular space at an inner periphery of the annular combination member by using these two communicating passages. When a passage axis where the two communicating passages are positioned is made substantially orthogonal to a resin injection direction, the resin can be more effectively filled into the annular space.
