description To provide an optical filter device that is thinner in an optical axis direction.SOLUTION: An optical filter device (1) includes: first optical filter portions (202, 203); a first holding frame (201) that holds the first optical filter portions; a first guide bar (204) and a second guide bar (205) that support the first holding frame so as to slide it; second optical filter portions (302, 303) arranged parallel to the first optical filter portions; a second holding frame (301) that holds the second optical filter portions; a third guide bar (304) and a fourth guide bar (305) that support the second holding frame so as to slide it; a first housing (10) that covers the first holding frame; and a second housing (20) that covers the second holding frame. The first holding frame is sandwiched between the first housing and one of the first guide bar and the second guide bar and is slid, and the second holding frame is sandwiched between the second housing and one of the third guide bar and the fourth guide bar and is slid.SELECTED DRAWING: Figure 4 【課題】光軸方向の厚みがより薄い光学フィルタ装置を提供する。【解決手段】光学フィルタ装置(1)は、第1光学フィルタ部(202、203)と、第1光学フィルタ部を保持する第1保持枠(201)と、第1保持枠を摺動可能に支持する第1ガイドバー(204)および第2ガイドバー(205)と、第1光学フィルタ部に平行に配置される第2光学フィルタ部(302、303)と、第2光学フィルタ部を保持する第2保持枠(301)と、第2保持枠を摺動可能に支持する第3ガイドバー(304)および第4ガイドバー(305)と、第1保持枠を覆う第1筐体(10)と、第2保持枠を覆う第2筐体(20)とを有し、第1保持枠は、第1筐体と、第1ガイドバーまたは第2ガイドバーに挟持されて摺動し、第2保持枠は、第2筐体と、第3ガイドバーまたは第4ガイドバーに挟持されて摺動する。【選択図】図4
