Abstract: An electrical current sensor includes a first laminated body having a magnetic detection element disposed over a first substrate, a protective film formed over the first substrate and the magnetic detection element, and a coil formed over the protective film, and a second laminated body having a shield layer formed over a second substrate and which is formed by bonding the first laminated body and the second laminated body to each other with an adhesion layer interposed therebetween such that the magnetic detection element and the shield layer face each other.
