1. A molded coil being one of two molded coils disposed adjacent to each other without interposing any other molded coil, the molded coil comprising:
a winding part having a conductor stacked from a first turn to an n-th turn, where n is an integer of 2 or more;
a first terminal part that has a lead part extending from the first turn of the winding part in a first direction orthogonal to a stacking direction of the conductor in the winding part; and
a second terminal part that has a lead part extending from a portion of the n-th turn of the winding part in the first direction in the winding part, wherein:
the first terminal part includes a first tip including a first engaging part, the second terminal part includes a second tip including a second engaging part, and
at least one of the first tip or the second tip includes a protruding part that protrudes from the lead part in a second direction crossing the first direction and the stacking direction when viewed from the first direction, and a length of the protruding part is smaller than a width of the winding part when viewed from the first direction.
