PURPOSE:To obtain a highly reliable sensor, which is stable against moisture and the like, by using an active metal alloy, in which In, Zn and Sb are added in Pb and Sn, as a sealing material for a solid image sensor element. CONSTITUTION:An annular sealing material 7 made of an active metal alloy, in which In, Zn and Sb are added in Pb and Sn, is held between a light transmitting glass plate 6 and the open end surface of a package 1. Pressure is applied and the device is heated to a temperature of 145-150 deg.C, which is lower than the melting point of the sealing material 7 at a rate of 1 deg.C/sec. When displacement is stopped, the heating is stopped. The device is cooled down to 120 deg.C or less. Pressure is removed and the device is completed. |
