A magnetic sensor has a pair of Hall elements formed in spaced-apart relationship on a front surface of a semiconductor substrate. A die pad is bonded to a back surface of the semiconductor substrate and overlaps the Hall elements. The die pad has formed therein a magnetic converging plate holder having a recessed portion, and a magnetic converging plate having the same shape and size as the recessed portion is fitted in the recessed portion of the magnetic converging plate holder.

Provided are a magnetic sensor and a method of manufacturing the same. In the magnetic sensor and the method of manufacturing the same, a magnetic converging plate holder with a recessed pattern having the same shape and size as those of a magnetic converging plate is formed in a die pad of a package on which a semiconductor substrate having Hall elements, a circuit, and the like is to be arranged, the magnetic converging plate manufactured through processes different from those of the semiconductor substrate on which the Hall elements and the circuit are formed is inserted into the magnetic converging plate holder, and the semiconductor substrate having the Hall elements, the circuit, and the like is arranged on the resultant so that a back surface thereof faces the die pad and the magnetic converging plate.
