Pressure sensor with waterproof structure and electronic device including the same

An electronic device comprising:

• a housing including at least one opened surface;
• a touchscreen display disposed in an interior space of the housing, at least a portion of the touchscreen display being exposed through the opened surface of the housing;
• a pressure sensor disposed between the touchscreen display and the housing, the pressure sensor being configured to detect an external pressure applied to the touchscreen display;
• and
• at least one processor electrically connected to the pressure sensor,
• wherein the pressure sensor includes:
• a first electrode plate disposed in parallel to the touchscreen display and having a first size and a first shape;
• a second electrode plate having a size and a shape that are the same as or similar to the first size and the first shape and facing the first electrode plate;
• a dielectric layer disposed in a first area between the first electrode plate and the second electrode plate;
• and
• a waterproof member disposed in a second area corresponding to a peripheral area of the first area and at least partially enclosing a space between a lower surface of the first electrode plate and an upper surface of the second electrode plate.
