PROBLEM TO BE SOLVED: To provide a press-fit sealed electronic part which is prevented from generating whiskers and capable of keeping a joint surface between a sealing canister and a plug unit airtight, and to provide a method of manufacturing the same. SOLUTION: The press-fit sealed electronic part is equipped with an electronic part 10, the plug unit 20, and a canister unit 30 which is sealed up by press-fitting the plug unit 20 to it. The plug unit 20 and the canister unit 30 are brought into close contact with each other through tin-free alloy layers 21 and 32. The method of manufacturing the press-fit sealed electronic part comprises processes of forming the plug unit 20 and the canister unit 30 by the use of a nickel silver material, plating them with tin-copper plating material 40, forming copper-zinc alloy layers 21 and 32 on an interface between the nickel silver material and the tin-copper plating material 40 by thermal treatment, exposing the copper-zinc alloy layers 21 and 32 to the outside by removing the tin-copper plating material, and bringing the plug unit 20 and the canister unit 30 into close contact with each other through the copper-zinc alloy layers 21 and 32 to subject them to press-fit sealing.
