Kinetic inductance detector (KID) is a promising technology for astronomy with high sensitivity, microsecond timing and intrinsic multiplexing readout properties. Based on these advantages, a wide range of application has been proposed from millimeter to X-ray. With simple fabrication and frequency domain multiplexing readout, hundreds of KID pixels could be easily read out with single cable. In the last decade, KID has been developed rapidly. This talk will introduce the recent development of KIDs for frequency range from 100 GHz to 1 THz. Recent development for NIKA2 instrument at IRAM 30-m telescope will also be presented.
