Claim 11:
12. A coil device comprising:
a first conductor including a first outer mounting part formed at one end and a second outer mounting part formed at the other end;
a second conductor disposed inside the first conductor and including a first inner mounting part formed at one end and a second inner mounting part formed at the other end;
a core for internally arranging the first conductor and the second conductor; and
a resin spacer including:
a first side insulating part disposed between the first outer mounting part and the first inner mounting part; and
a second side insulating part disposed between the second outer mounting part and the second inner mounting part, wherein

the resin spacer includes an inner insulating part disposed between one end and the other end of the second conductor and disposed between a bottom surface of the core and the first inner mounting part or between the bottom surface of the core and the second inner mounting part,
a first gap is formed between the first side insulating part and one end of the inner insulating part in a first direction,
a second gap is formed between the second side insulating part and the other end of the inner insulating part in the first direction,
the first side insulating part, the second side insulating part, and the inner insulating part extend in a second direction perpendicular to the first direction, and
the resin spacer includes a first connection part connecting one ends in the second direction of the first side insulating part, the second side insulating part, and the inner insulating part along the first direction.
