A light emitting device (100) includes a light emitting element (10) having an emission peak wavelength in a range of 380 nm or more and 490 nm or less, and a red fluorescent material (70) which is excited by the light from the light emitting element (10) to emit light having at least one light emission peak wavelength in a range of 580 nm or more and 680 nm or less, wherein a ratio of the photon flux R of red light in a range of 620 nm or more and 700 nm or less to the photon flux B of blue light in a range of 400 nm or more and 490 nm or less, the ratio R/B is in a range of more than 20 and 200 or less.
