PURPOSE:To improve the mass productivity of a detector, by forming stanchions having grooves at prescribed intervals longitudinally and transversely on the main plane of an original plate for a support base, and coating an adhesive agent thereon then placing a pyroelectric wafer on the same and dividing the pyroelectric wafer and the original plate for the support base in the positions passing the grooves. CONSTITUTION:Many stanchions 9 are beforehand formed by acid etching at prescribed intervals longitudinally and transversely on the top surface of an original plate 6' for a support base, and further, grooves 10 are formed in a cruciform shape in longitudinal and transverse directions to the respective stanchions 9. An epoxy adhesive agent 8 is coated only on the top surface of each stanchion 9 and a pyroelectric wafer 1' is placed thereon in a way that a rear electrode 3' is faced downward. The 1st front electrode 2a and the 2nd front electrode 2b are vacuum deposited on the surface of the wafer 1' after the adhesive 8 is allowed to cure by heating. Thereafter the wafer 1', the plate 6', etc. are diced in the positions passing the grooves 10. |
