ABSTRACT:
A humidity sensor includes a resin molding body having a wall portion as a barrage, a chip having at least a humidity sensing function and fixed to a portion of the resin molding body inside the wall portion, and a terminal conductor insert-molded in the resin molding body and partially leaded to an exterior of the resin molding body. Here, the terminal conductor is electrically connected to the chip inside the wall portion of the resin molding body. In the humidity sensor, a protecting material having a humidity sensing property is filled in the wall portion and covers an entire electric connecting portion of the chip and the terminal conductor. The structure of the humidity sensor can be suitably used for a composite sensor including a chip having a humidity sensing function.
