Abstract
A press-fit sealed electronic component includes an electronic component, a plug to be equipped with the electronic component, and a tube to be sealed by press-fitting the plug, wherein the plug is brought into close contact with the tube through a tin-free alloy layer. A method for producing a press-fit sealed electronic component includes the steps of forming the plug and the tube with a nickel silver material, forming a tin-copper layer by plating on each surface of the plug and the tube, forming a copper-zinc alloy layer at the interface between the nickel silver material and the tin-copper layer by heat treatment, removing the tin-copper layer remaining on the copper-zinc alloy layer to expose the copper-zinc alloy layer, and bringing the plug into close contact with the tube through the exposed copper-zinc alloy layer to seal the tube by press-fit.
