An optical measurement apparatus 1 includes a light source unit 22 that supplies irradiation light to be emitted to the living tissue, a measurement unit 24 that measures reflection light and/or scattering light from the living tissue, an operation unit 27a that performs multiple types of operation processes based on a result of the measurement performed by the measurement unit, a validity evaluator 27b that evaluates, based on an operation result of one of the multiple types of operation processes performed by the operation unit 27a, whether the result of the measurement performed by the measurement unit 24 is valid, an output unit 26 that outputs at least a result of the evaluation performed by the validity evaluator, an input unit 25 that inputs instruction information containing an instruction to adopt the result of the measurement performed by the measurement unit, and a determination unit 27c that determines, based on the result of the evaluation performed by the validity evaluator and the instruction information input by the input unit, whether to adopt the result of the measurement performed by the measurement unit 24.
