A medical device including a silicone hydrogel which is less likely to harden due to drying, and which is less likely to cause stimulation at a site in contact with a human body, is disclosed. The medical device includes a silicone hydrogel satisfying the following conditions: (1) the water content in hydrous state is within the range of 10% by mass to 70% by mass； (2) the content of silicon atoms with respect to the total mass in dry state is within the range of 8% by mass to 30% by mass； and (3) the tensile elastic modulus in dry state is within the range of 0.1 MPa to 3.5 MPa.
