Abstract: A vibration sensor according to an embodiment includes a substrate, a convex member, and a piezoelectric element. The substrate includes a first principal surface and a second principal surface. The substrate transmits vibration. The convex member is fixed on the first principal surface. The piezoelectric element is disposed within a second fixing region on the second principal surface. The second fixing region corresponds to, in a planar view, a first fixing region of the substrate on which the convex member is fixed.

Abstract: A gas detection element includes a crystal oscillator and a gas adsorption film formed on the crystal oscillator. The gas adsorption film has a thickness that causes the detection element to have a crystal impedance of no more than 10 times the crystal impedance of the crystal oscillator on which the gas adsorption film is not formed. A resonance frequency variation of the gas detection element due to humidity variation can be kept within a certain range.

Abstract: [Object] To provide a management apparatus and an air conditioning management system by which the objectivity of a comfort level evaluation relating to a smell in a room can be enhanced and a comfort level can be evaluated also with respect to an unknown smell.[Solving Means] A management apparatus according to an embodiment of the present invention includes a detecting unit, an input unit, a storage unit, and a control unit. The detecting unit detects a smell in a room. The input unit is operated by a user who enters the room and acquires a sensory evaluation of each user which relates to the smell in the room when the user enters the room. The storage unit accumulates evaluation data obtained by associating an output of the detecting unit and an output of the input unit with each other and stores a plurality of attributes relating to a comfort level of the smell in the room, the attributes being classified on the basis of the evaluation data. The control unit determines which of the plurality of attributes the output of the detecting unit belongs to.
