Electronic device including camera module

An electronic device comprising:

• a housing;
• at least one optical module disposed in an inner space of the housing;
• a window bracket disposed in the inner space of the housing to be at least partially connected to an outside of the electronic device, the window bracket comprising
• a flange comprising at least one opening disposed at a position corresponding to the at least one optical module,
• a boss extending to surround an edge of the at least one opening at a height from the flange, and
• a stepped portion provided along an edge of the boss and comprising a step surface and an inner side surface extending in a perpendicular direction relative to the step surface;
• and
• a window attached to the window bracket via an adhesive member-disposed on at least a portion of the step surface and comprising an outer surface, an inner surface facing away from the outer surface, a window side surface surrounding a space between the outer surface and the inner surface and an inclined surface connecting the inner surface and the window side surface,
• wherein the inner side surface comprises a recess defined having a depth,
• wherein a height of the recess from the step surface to a first point where the recess starts is greater than a thickness of the adhesive member, and
• wherein a height from a point where the inclined surface and the window side surface meet to the step surface is higher than a height from the first point to the step surface.
