PROBLEM TO BE SOLVED: To provide an interference filter in which connection strength of substrates is improved, connecting process is made easy and a required wavelength is accurately separated, a colorimetry sensor, a colorimetry module and a method of manufacturing the interference filter. SOLUTION: The interference filter includes: a first substrate 51; a second substrate 52 which is disposed while being opposed to the first substrate 51 and connected to the first substrate 51; a pair of mirrors 56, 57 which are provided on the opposing faces of the first substrate 51 and the second substrate 52 respectively and disposed oppositely to each other; connection faces 513, 524 which are provided on the opposing faces of the first substrate 51 and the second substrate 52 respectively and connected to each other by an optical contact; a first groove part 514A which is formed on the connection face 513 of the first substrate 51 and into which an adhesive for bonding the connected faces 513 and 524 flows; and an adhesive injection hole 524A and an adhesive discharge hole 524B which are formed on the second substrate 52 to communicate the first groove part 514A with the outside.
