1. A camera module comprising:
a first refractive member configured to reflect or refract light that is incident on the first refractive member in a first direction, in a second direction intersecting the first direction;
a second refractive member configured to reflect or refract the light that is reflected or refracted by the first refractive member and is incident on the second refractive member in the second direction, in a third direction intersecting the second direction;
an image sensor configured to detect the light that is reflected or refracted by the second refractive member and is incident on the image sensor in the third direction; and
at least one optical member provided between the first refractive member and the second refractive member,
wherein the at least one optical member comprises a dummy member extending in the second direction and configured to transmit light traveling in the second direction, and a first light shielding member provided on at least a portion of an outer circumferential surface of the dummy member,
wherein the dummy member is configured to guide the light that is reflected or refracted by the first refractive member to be incident on the second refractive member in the second direction,
wherein the first light shielding member and the outer circumferential surface of the dummy member face the third direction, and
wherein the first light shielding member is configured to absorb, scatter or reflect the light that is reflected or refracted by the first refractive member to block a portion of the light from being directly incident on the image sensor.
