The present invention provides a high-pressure discharge lamp having a long life.A high-pressure discharge lamp (100) comprises a light emitting part (4); first and second sealing parts (6, 8); first and second electrodes (10, 11); a first conductive lead (21) wound around the first sealing part; a first lead wire (22) electrically connecting the first conductive lead to the first electrode; a second conductive lead (25) wound around the second sealing part; and a second lead wire (26) connecting the second conductive lead to the first electrode. The second lead wire detours the light emitting part to avoid being affected by heat.After the lamp is turned off, the temperature of base parts of the electrodes immediately falls, and much mercury can be collected in the vicinities of the base parts.
