Camera module including magnet interacting with both coil for performing focusing function and coil for performing shake compensation function

A camera module comprising:

• a housing comprising a first housing and a second housing disposed under the first housing;
• a barrel disposed in the first housing;
• a first elastic member connecting the barrel and the first housing;
• a second elastic member coupled with the first housing and the second housing;
• a lens assembly disposed in the barrel;
• a first coil disposed on an outer side of the barrel;
• a magnet disposed on the first housing;
• and
• a second coil disposed on the second housing,
• wherein the first coil faces the magnet in a horizontal direction and the second coil faces a lower surface of the magnet in a vertical direction such that the first coil and the second coil share and interact with the magnet,
• wherein the lens assembly comprises at least five lenses,
• wherein a first lens disposed closest to an object side among the at least five lenses comprises a positive refractive power and a convex surface facing the object side,
• wherein a second lens disposed second from the object side among the five lenses comprises a meniscus shape,
• wherein a third lens disposed third from the object side among the five lenses comprises a meniscus shape,
• wherein a fourth lens disposed fourth from the object side among the five lenses comprises a meniscus shape,
• wherein at least one of an object side surface of the fourth lens and an image side surface of the fourth lens comprises at least one aspheric inflection point,
• wherein a side portion of the first housing is overlapped with a portion of the second elastic member in the horizontal direction,
• wherein the first housing comprises the side portion and an upper portion extending from an upper end of the side portion in the horizontal direction,
• wherein the magnet comprises the lower surface facing an upper surface of the second coil, an upper surface facing the upper portion of the first housing, a first side surface facing the first coil, and a second side surface facing the side portion of the first housing,
• wherein the first coil faces the first side surface of the magnet in the horizontal direction, and
• wherein, measured in the vertical direction, a width of the first side surface of the magnet is greater than a width of a surface of the first coil facing the first side surface of the magnet.
