Electronic component
An electronic component includes a body; a coil including a first coil conductor, a second coil conductor, and a via conductor; and an internal magnetic circuit provided on an inner peripheral side of the coil. The first coil conductor is formed of a plurality of straight portions and a plurality of arc-shaped portions and is substantially spiral shaped. A portion of the first coil conductor located furthermost toward the inner peripheral side is an arc-shaped first connection portion. The second coil conductor is formed of a plurality of straight portions and a plurality of arc-shaped portions and is substantially spiral shaped. A portion of the second coil conductor located furthermost toward the inner peripheral side is an arc-shaped second connection portion. An end of the via conductor is connected to the first connection portion and another end of the via conductor is connected to the second connection portion.

a body composed of an insulator;
a coil including a first coil conductor provided on a first plane located inside the body, a second coil conductor provided on a second plane parallel to the first plane inside the body so as to be superposed with the first coil conductor when seen from an orthogonal direction orthogonal to the first plane, and a via conductor connecting the first coil conductor and the second coil conductor to each other; and
an internal magnetic circuit provided on an inner peripheral side of the coil; wherein
the first coil conductor is substantially spiral shaped as a whole and includes a first portion, which is located furthermost toward the inner peripheral side of the first coil conductor and is substantially arc-shaped, a second portion, which has one end connected to the first portion and is substantially shaped like a straight line, a third portion, which is connected to another end of the second portion and draws a substantially semicircular arc having a larger radius than an arc drawn by the first portion, and a fourth portion, which has one end connected to the third portion, has the same length as the second portion and is substantially shaped like a straight line, and
the second coil conductor is substantially spiral shaped as a whole and includes a fifth portion, which is located furthermost toward the inner peripheral side of the second coil conductor and is substantially arc-shaped, a sixth portion, which has one end connected to the fifth portion and is substantially shaped like a straight line, a seventh portion, which is connected to another end of the sixth portion and draws a substantially semicircular arc having a larger radius than an arc drawn by the fifth portion, and an eighth portion, which has one end connected to the seventh portion, has the same length as the sixth portion and is substantially shaped like a straight line,
