Provided is a phosphor excellent in light emission characteristics when excited by light in the near ultraviolet to blue region, and can be suitably used in combination with, for example, a near ultraviolet or blue LED. The phosphor is represented by the following composition formula (1). M 3-p Eu p (PO 4 ) q (1) (Here, M is a divalent metal element and contains at least Sr and Ca. Further, p and q satisfy the following formula. 0.02 <p ≦ 0.1 1.6 ≦ q ≦ 2.4) [Selection figure] None |
