A choke coil equipped with a bobbin which is easy to form, which is resistant to mechanical impacts and which is light in weight and inexpensive. A bobbin 2 is formed, for example, by fitting or gluing together a bobbin member 21 formed of a magnetic substance and a bobbin member 22 formed of a non-magnetic substance. The magnetic substance bobbin member 21 is equipped with a core portion 23a with flange members 24a and 25a at the ends thereof and a flange member 26a provided in the central section thereof. The non-magnetic substance bobbin member 22 is equipped with a tubular portion 23b with flange members 24b and 25b provided at the ends thereof and a flange member 26b provided in the central section thereof. A tubular body portion 23 of the bobbin 2 is formed by the core portion 23a and the tubular portion 23b, and flange portions 24, 25 and 26 of the bobbin 2 are respectively formed by flange members 24a/24b, 25a/25b and 26a/26b.
