Abstract
A method of manufacturing resonation device (a quartz crystal oscillator) includes the steps of applying a thermosetting thermal insulating connection material and an electrically-conductive connection material, which is higher in curing temperature than the thermosetting thermal insulating connection material, on a principal surface of a substrate, mounting fixation terminals of a resonator (a quartz crystal resonator), which has a heating element, and to which the fixation terminals and connection terminals are connected, in application positions of the insulating connection material on the substrate, and connection terminals in application positions of the electrically-conductive connection material, and heating the insulating connection material and the electrically-conductive connection material based on a reflow profile to make the insulating connection material and the electrically-conductive connection material cure in this order.
