[Object] To provide a magnetic detection element having stable characteristics in which, in particular, the formation area of a resist layer that covers an insulation protection layer is adjusted so that a magnetic detection element and a connection layer can be formed with high precision on a surface having small steps and the resist layer can be prevented from being separated, and to provide a method of manufacturing the same. [Solving Means] A resist layer 42 is disposed so as to overlap an interconnection layer 35 through the insulation protection layer 41. A lower edge portion 42b1 of a hole formation surface 42b of the resist layer 42 is disposed on the insulation protection layer 41 so that the resist layer 42 does not extend to an exposed surface 35b of the interconnection layer 35. Thereby, a magnetic detection element 10, electrode layers connected to the magnetic detection element 10, and a lead layer 17 can be formed on a smooth insulating surface with small steps, and also the resist layer 42 can be prevented from being separated. As a result, a magnetic detection device having stable characteristics can be obtained.
