This invention discloses a mid-to-far-infrared narrowband light source for MEMS, comprising a substrate, a suspension support layer, a heating resistor layer, and a radiation functional layer. The substrate is a silicon substrate. The suspension support layer is fixed to the substrate by anchor points. The heating resistor layer is disposed on the suspension support layer, and the radiation functional layer is disposed above the heating resistor layer. The suspension support layer and the heating resistor layer have Y-shaped grooves forming a Y-beam suspension structure. The Y-beam suspension structure is connected to the substrate by anchor points to form thermal isolation. The surface of the radiation functional layer has a periodically arranged array of micro / nano structures.
