A thermal detector has a substrate, a thermal detector element having a light-absorbing film, and a support member. The support member has a mounting part mounting the thermal detector element, a first arm part having one end that is linked to one end of the mounting part and another end that is supported on the substrate, and a second arm part having one end that is linked to the other end of the mounting part and another end that is supported on the other end of the substrate. A plurality of wirings electrically connected with the thermal detector element are provided on the first arm part, and the length of the second arm part is shorter than the length of the first arm part.
