The present disclosure provides a time-of-flight camera, comprising a light-emitting module and a light-receiving module. The light-emitting module comprises a light source component, a light-reflecting component, and a light-diffusing component. The light source component emits a first light in a first direction. The light-reflecting component and the light-diffusing component are disposed on the light path of the first light. A second light formed by the first light passes through the light-reflecting component and the light-diffusing component. The second light travels toward a second direction to an object to be measured. The object to be measured reflects the second light. The first direction is intersecting with the second direction. The light-receiving module receives the reflected second light and performs the function of sensing.
