<P>PROBLEM TO BE SOLVED: To provide a terahertz wave detector, an imaging device and a measuring device capable of being reduced in size in comparison with a prior art. <P>SOLUTION: A terahertz wave detector 1 comprises: a wavelength filter 2 which selectively converts a terahertz wave with a predetermined wavelength into heat; and a detecting section 3 which converts the terahertz wave with the predetermined wavelength transmitted through the wavelength filter 2 into heat and detects the heat. The wavelength filter 2 includes: a metal film 5 having a plurality of holes 51 communicating with an incident surface 52 to which the terahertz wave is made incident and with an emitting surface 53 from which the terahertz wave with the predetermined wavelength is emitted; and a terahertz wave absorbing layer 4 containing a material absorbing the terahertz wave between the detecting section 3 and the metal film 5. The plurality of holes 51 is provided at a predetermined pitch in a direction perpendicular to a normal of the incident surface 52. <P>COPYRIGHT: (C)2013,JPO&INPIT |
