Abstract
A magnetic detection apparatus includes a first block, a second block, and an exterior resin covering the first block and the second block. The first block includes a magnetoresistive element for detecting a change in a magnetic field that varies in accordance with movement of a rotating member, electronic components forming a protection circuit against external noise, a first lead frame electrically connected with the electronic components, and a first base in which the electronic components, the first lead frame and the magnetoresistive element are sealed with a resin. The second block includes a magnet arranged in opposition to an object to be detected for generating a magnetic field, a second lead frame electrically connected with the first lead frame and having a connector terminal for outputting an output signal of the magnetoresistive element to an external member, and a second base in which the second lead frame is sealed with a resin.
