The present invention relates to a multilayer optical recording medium having N (N>=5) boundary surfaces by which incident light can be reflected, so as to prevent multiple beam interference which is a practical problem caused by stray light. In the present invention, each of M (M<=N) boundary surfaces selected from the N boundary surfaces is defined as Li (i=0, 1, ..., M, wherein an interface having a smaller value i is formed at a lower layer position farther away from the uppermost surface which is a light-incident surface). When j < k <= l < m <= M, for a boundary surface Lk, a boundary surface Lm, a boundary surface Ll and the above boundary surface Lj that generate stray light by reflecting three times via Lk (or Ll) -> Lm -> Ll (or Lk) in a case where light having a wavelength [lambda] is focused to the boundary surface Lj as a target by using an objective lens having a numerical aperture NA, the following condition is satisfied: a difference, an absolute value of Sj-k deducted by Sl-m, between the total sum Sj-k of the thicknesses of spacers formed between the boundary surface Lj and the boundary surface Lk, and the total sum Sl-m of the thicknesses of spacers formed between the boundary surface Ll and the boundary surface Lm is greater than n [lambda] /NA2 (wherein n is the refractive index of the spacers).
