Method for manufacturing spectroscopy module, and spectroscopy module

A method for manufacturing a spectroscopy module which is provided with a body portion through which light is allowed to transmit, a spectroscopic portion that disperses a light made incident into the body portion from a side of a predetermined plane of the body portion, and reflects lights to the side of the predetermined plane, and a light detecting element which detects the lights dispersed by the spectroscopic portion, the method comprising the steps of:

• electrically connecting the light detecting element including a light passing hole through which a light advancing to the spectroscopic portion passes, and a guide portion that surrounds the light passing hole and partially leads to an outer edge of the light detecting element, to a wiring formed on the predetermined plane by face-down bonding;
• forming a first resin layer along the guide portion between the body portion and the light detecting element;
• and
• forming a second resin layer so as to make the second resin layer face a light detecting portion of the light detecting element, at an outer side of the first resin layer between the body portion and the light detecting element.
