Claim 6:
7. An actuator comprising:
a support body comprising:
a coil comprising a winding part and a lead part extended from the winding part;
a coil holder which holds the coil; and
a board which is supported by the coil holder;

a movable body comprising a magnet facing the winding part;
a connection body which relatively movably connects the movable body with the support body; and
a magnetic drive mechanism which comprises the coil and the magnet and is structured to relatively move the support body and the movable body;
wherein the coil holder comprises a coil holding part which holds the winding part and a board support part which supports the board on an outer side in a radial direction of the coil holding part;
wherein a board surface of the board comprises a land with which the lead part is connected;
wherein the board support part comprises a recessed part at a position overlapping with the board when viewed in a direction along the board surface; and
wherein the lead part is extended from the winding part to the land via the recessed part and comprises a resiliently bent portion which is resiliently bent in an inside of the recessed part,
wherein in a case that a direction where the winding part and the magnet face each other is defined as a first direction, and two directions perpendicular to the first direction and perpendicular to each other are defined as a second direction and a third direction,
the coil holding part and the board support part are arranged in the second direction,
the board surface faces an opposite side to the coil holding part in the second direction,
the board comprises:
a wiring connection part comprising the land; and
a pair of leg parts which are protruded to one side in the first direction from both end portions in the third direction of the wiring connection part,

the board support part comprises:
a pair of slits into which both end edges in the third direction of the board are respectively inserted from an other side in the first direction; and
an insertion part which is inserted from the one side in the first direction to a cut-out opening of the board sectioned by the pair of the leg parts and the wiring connection part,

the insertion part comprises a tip end face which is abutted with the wiring connection part, and
the recessed part is provided on the tip end face,, wherein
the coil holder is made of resin,
the pair of the leg parts comprise a pair of protruded parts which are contacted with the insertion part from both sides in the third direction,
in a state before the insertion part is inserted to the cut-out opening, the pair of the protruded parts face each other in the third direction, and
a distance in the third direction between the protruded parts is narrower than a width in the third direction of the insertion part,, wherein
the insertion part comprises:
a pair of inclined faces which are inclined in a direction separated from the wiring connection part toward a direction separated from the tip end face on both sides in the third direction of the tip end face; and
a pair of side faces which are extended to an opposite side with respect to the wiring connection part in the first direction from ends of the inclined faces on an opposite side to the tip end face, and

in a state before the insertion part is inserted to the cut-out opening, a distance of the protruded parts facing each other in the third direction is wider than a width in the third direction of the tip end face and is narrower than a distance in the third direction between the pair of the side faces.
