1. 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 the coil holding part is a hole which accommodates the winding part;
wherein the coil holder comprises a guide groove which guides the lead part, and the guide groove communicates with 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 at a position communicating with the guide groove;
wherein the guide groove comprises a first groove portion which is connected with the recessed part in a depth shallower than the recessed part;
wherein the recessed part is recessed from the first groove portion to an opposite side to the land; 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 deformably disposed in an inside of the recessed part on the opposite side to the land with respect to the first groove portion.
