A biological information measurement device includes: a first sensor module (21) which includes one or multiple light-emitting elements (30, 31, and 32) emitting light and one or multiple light-receiving elements (40 and 41) receiving light emitted from the light-emitting elements (30, 31, and 32) and outputting a signal of an intensity corresponding to an amount of light to be received; and a second sensor module (22) which includes one or multiple light-emitting elements (33) emitting light, wherein at least one light-receiving element of the first sensor module (21) receives light emitted from at least one light-emitting element of the first sensor module (21) and reflected by an organism and receives light which has been emitted from at least one light-emitting element of the second sensor module (22) and which has been transmitted through an organism.
