A lamp and a method for manufacturing the same are proposed. The lamp according to the invention includes a light emitting part equipped with a light emitting body; a fixed shell connected to the light emitting part to support the light emitting part; terminal pins inserted and installed in the fixed shell, one ends being electrically connected to the light emitting body, and a plurality of sealing parts forming a surrounding environment surrounding the terminal pins in the fixed shell and formed to have a plurality of stepped parts along the extension direction of the terminal pins, and at least two of the plurality of stepped parts being made of different sealing materials and sealing the surrounding environment of the terminal pins. Therefore, according to the embodiment of the invention, sealing performance or airtight compactness of the circumference of outer circumferential surfaces of the terminal pins is enhanced, and occurrence of electric leakage of the surrounding environment of the terminal pins is prevented. Thus, maintaining and processing a heater block and processing a cavity become easier under high vacuum.
