Claim:
1. An optical analysis cell, comprising: a pair of light transmitting plates that sandwich and hold a sample having predetermined viscoelasticity between mutually opposed inward surfaces without a spacer that contacts both of the inward surfaces to fix a separation distance between the inward surfaces, a distance fixing member having a pair of opposed surfaces provided separately from each other by a predetermined distance, wherein the light transmitting plates are arranged between the pair of opposed surfaces such that when the sample having the predetermined viscoelasticity is disposed between the light transmitting plates, an elastic force of the sample is received by the light transmitting plates, and thereby outward surfaces on sides opposite to the inward surfaces of the light transmitting plates are pressed against the opposed surfaces of the distance fixing member to fix the separation distance between the inward surfaces, whereby the light transmitting plates do not contact each other when the light transmitting plates are pressed against the opposed surfaces of the distance fixing member.
