The biological information detecting apparatus includes a face detecting section detecting the face of a person from an image signal, an expression detecting section detecting an expression of the person from the image signal of the region of the face to calculate an expression feature amount, a pulse wave detecting section detecting a pulse wave of a blood flow of the person from the image signal of the region of the face, a scoring section calculating a score of the expression of the person based on the expression feature amount, a coaching section generating an expression guide, and a display section displaying the expression guide, and the display section further displays biological information indicating a state of the autonomic nerve of the person calculated based on the pulse wave after displaying the expression guide, and the score calculated based on the expression feature amount.
