1. An inductor component comprising:
an element body;
a first inductor and a second inductor disposed in the element body;
first and second columnar wirings that are embedded in the element body with end surfaces exposed from a first principal surface of the element body and that are electrically connected to the first inductor, and third and fourth columnar wirings that are embedded in the element body with end surfaces exposed from the first principal surface of the element body and that are electrically connected to the second inductor;
a first external terminal in contact with the end surface of the first columnar wiring, a second external terminal in contact with the end surface of the second columnar wiring, a third external terminal in contact with the end surface of the third columnar wiring, and a fourth external terminal in contact with the end surface of the fourth columnar wiring, the first external terminal being located closer to the third external terminal than the fourth external terminal; and
an insulating film disposed on the first principal surface of the element body, wherein
a shortest distance between the first external terminal and the third external terminal is longer than a shortest distance between the first columnar wiring and the third columnar wiring, and
the insulating film covers a portion of the end surface of the first columnar wiring not in contact with the first external terminal and a portion of the end surface of the third columnar wiring not in contact with the third external terminal.
