PROBLEM TO BE SOLVED: To enhance the sensitivity of magnetic field detection in a magnetic field detection device. SOLUTION: The magnetic field detection device 3 includes a substrate 5 and a coiled conductive part 9, and the coiled conductive part 9 is formed by arranging each via hole 12, 19, 21, each bonding wire 18, 23, etc. into the shape of a spiral whose axis is O-O. As a result, the area of a loop in the coiled conductive part 9 can be increased, and upon detecting a magnetic field, an electromotive force generated in the coiled conductive part 9 is increased, so that the sensitivity of magnetic field detection is enhanced.
