An infrared detection element includes a substrate, a lower electrode layer, a pyroelectric layer, and an upper electrode layer. The lower electrode layer is fixed to the substrate, and the pyroelectric layer is formed on the lower electrode layer. The upper electrode layer is formed on pyroelectric layer. The lower electrode layer contains pores therein and has a larger thermal expansion coefficient than the pyroelectric layer.
